“…In addition, smooth blasting, presplitting blasting and buffer blasting are gradually used in underground engineering. With the introduction of NATM [65,66], the excavation method of hand drill, free blasting and scaffolding support was replaced by the technology of combined bolting and shotcrete. In 1985, the rock anchored beam technology was introduced into the Lubuge hydropower station in Norway [67], and further improved and developed in China [52].…”

To recommend the excavation procedures and design parameters for underground powerhouses, excavation procedures of fifty-one underground powerhouses in China were summarized and analyzed based on in situ stress conditions. Firstly, the complex stress environment in China was introduced and fifty-one underground powerhouses with their engineering scale, size, lithology, rock classification and in situ stress level were listed in detail. Subsequently, to evaluate the influence of in situ stress levels on excavation procedure design, the correlation between excavation procedures and in situ stress level in three main excavation zones were analyzed accordingly. Moreover, to provide the excavation design recommendations, the strength–stress ratio (SSR) was promoted to analyze and recommend the design parameters, and the blasting excavation design based on the stress transient unloading control was also supplemented. The results show that excavation procedures have different priorities under different in situ stress levels, and the design parameters show an obvious relationship with in situ stress levels. Moreover, the excavation procedure parameters are suggested to adjust accordingly under different SSR. The discussion of influencing factors and specification ensures its rationality and accuracy. It is believed that the summary and recommendations can provide a good reference for excavation procedure optimization of underground powerhouse under high in situ stress.

“…In particular, the displacement change and stress status of surrounding rock structures are very complicated due to the influence of many factors, such as the structural characteristics, mechanical properties, physical parameters, the time of initial support structure, the way of the initial support structure and the construction method [5][6][7][8]. At the same time, the displacement and stress of the tunnel structure have obvious time and space effects during the whole construction process [9][10][11].…”

In order to obtain the change rule of surrounding rock structure displacement and supporting structure internal force with time during the construction of the low mountain ridge tunnel, this paper relies on the Xishan Tunnel Project as the background. During tunneling, the displacement around the tunnel, the subsidence of the surface, the internal force of the steel arch and the pressure between the two layers of support are monitored dynamically. According to the above monitoring and measurement data, and the monitoring data analysis and nonlinear regression fitting, the predicted trend curve is obtained, the displacement change rules and characteristics of various surrounding rocks of the tunnel are obtained, to ensure the construction safety and stability requirements of supporting structure, and to provide a reasonable opportunity for the construction of secondary lining.

“…The correlation management of construction data can further improve the construction efficiency. Du B et al Proposed a new data service system, which uses data management technology to establish the association relationship between data, and verified the effectiveness of the system through experiments (Du et al 2018). Based on the personnel safety data in construction, Shin D P and other scholars put forward relevant strategies on construction safety management to improve the construction progress (Shin et al 2018).…”

With the continuous expansion of the scale of urban rail transit construction projects, it is difficult to improve the coordination in construction and the relevance of construction data. In order to solve the problem of data association in construction, an urban rail transit construction data association management system oriented to BIM Technology is proposed. BIM is used to build a dynamic workflow collaboration architecture to manage the data in urban rail transit construction, so as to realize construction collaborative scheduling. In the test and analysis of the system, the comprehensive ability test of the system shows that the minimum response time of the system can be reduced to 1.2 ms. At the same time, the system has ideal visualization effect and obvious practical value in practical application. Therefore, the urban rail transit construction data association management system based on BIM can show ideal results in complex construction environment, which is of great significance to China's urban construction.
