“…In addition, the annual completed construction investment has reached a new record. However, with the rapid development of the metro, construction safety accidents occur frequently, which cause a large number of casualties and economic losses [3]. According to statistics, during the period from 2002 to 2016 (statistics to March 2016), 246 accidents occurred in metro station construction in China, of which metro station projects accounted for 57% [4].…”

Incorporating safety risk into the design process is one of the most effective design sciences to enhance the safety of metro station construction. In such a case, the concept of Design for Safety (DFS) has attracted much attention. However, most of the current research overlooks the risk-prediction process in the application of DFS. Therefore, this paper proposes a hybrid risk-prediction framework to enhance the effectiveness of DFS in practice. Firstly, 12 influencing factors related to the safety risk of metro construction are identified by adopting the literature review method and code of construction safety management analysis. Then, a structured interview is used to collect safety risk cases of metro construction projects. Next, a developed support vector machine (SVM) model based on particle swarm optimization (PSO) is presented to predict the safety risk in metro construction, in which the multi-class SVM prediction model with an improved binary tree is designed. The results show that the average accuracy of the test sets is 85.26%, and the PSO–SVM model has a high predictive accuracy for non-linear relationship and small samples. The results show that the average accuracy of the test sets is 85.26%, and the PSO–SVM model has a high predictive accuracy for non-linear relationship and small samples. Finally, the proposed framework is applied to a case study of metro station construction. The prediction results show the PSO–SVM model is applicable and reasonable for safety risk prediction. This research also identifies the most important influencing factors to reduce the safety risk of metro station construction, which provides a guideline for the safety risk prediction of metro construction for design process.

Mel'nick V., Karachun V., shybetskij V., fesenko s., shafarenko n. introductionIt is difficult to imagine a person's real life in big cities without the services of the «subway» and railway transport. Metropolitan can be called without exaggeration the most popular form of transport in Kyiv (Ukraine).For a day, the metropolitan subway carries up to 1.5 million passengers. For the majority of Kyivans, it remains the fastest and most reliable way to get to this or that point of the city. However, in terms of convenience and security, the Ukrainian subway slightly loses to its counterparts from more developed countries. The most loaded, at present, is Lisova station (Kyiv, Ukraine).In Kyiv, cases of people falling on rails are not rarebe it an attempt at suicide or an accident. When this happens, the movement of the train stops along the entire line, many are late for work, huge crowds accumulate at the stations, which then flow into the carriages. In the Tokyo Metro (Japan), along the platform are installed special fences, which prevent people from falling onto the rails.At the entrance to the platform apron and at the exit from it is necessary to be careful with the glass doors that open in both directions. A rush of air or due to the negligence of the person walking, it is possible to injure the limbs of the hands and head.The greatest danger for passengers on the platform is the train arriving at the station, which moves powerfully at high speed. When the train comes to the station, it drives so much air in front of you, the «wind» on the apron begins even before you see the fire of the train in the tunnel to your right.Thus, there is a significant technological risk of railway technology that is due to casual clutches of the passenger clothing surface on the edge of the platform with the side surface of the car body. A special danger occurs during peak hours, when the station is oversaturated by passengers and there is a danger of congestion at the edge of the platform (Fig. 1). This can lead to a forced collision of a person with the high-speed side of the car. Also, the next step is pulling the person under the wheels into the platform gap. This is due to the considerable adhesion of the moving surface of the person's clothing to the moving surface of the car body, as well as the fixed heels of the person's shoes with the platform surface.According to the official information of the Moscow subway, today, on all overloaded lines, the minimum possible interval is reached, which is 1.5 minutes. To make it even less impossible -this is dangerous, since it can lead to accidents.By 2017 in the Kyiv subway there were 18 cases of people falling on rails. Two people were killed. In 2017 half a billion passengers took advantage of the Kyiv subway.

“…As an important component of a nation's infrastructure, the value and importance of the tunnels is of great concern around the world [1]. For example, to improve urban traffic congestion and the quality of life of residents, more and more Chinese cities are building subways [2]. In addition, with the rapid development of China's high-speed railway network in recent years, mountain railway tunnels are also being built [3].…”

Water inrush is one of the main disasters occurring during tunnel construction in complex geological areas: once it happens, it can cause economic losses, casualties, and delay. Based on risk analysis and management, a risk control scheme is proposed as an effective means to control the risk of such a disaster; however, there are some deficiencies in existing research because the impacts of human factors on the risk of water inrush, dynamic changes in risk information during construction, and the diversity of types of water inrush are neglected. To enrich the research results of water inrush risk control and improve the effect of water inrush risk control, we first use the advantages of Bayesian network to analyse risk events, construct a Bayesian network structure chart of water inrush risk during construction, and propose a fuzzy probability risk analysis model for water inrush. The model can quickly track changes in risk information and diagnose the cause of water inrush disasters while providing an early warning thereof. In addition, considering that the diversity of water inrush types leads to differences in water inrush mechanisms, we believe that the formulation of any water inrush risk control scheme must be combined with water inrush mechanism analysis; therefore, we take a nondefect generated water inrush in front of the tunnel as a representative case and analyse the possible mechanism of water inrush through the stability analysis of the water-resisting strata. Then, based on the results of risk analysis and an analysis of the water inrush mechanism, a reasonable risk control scheme for water inrush is derived.
