The site construction management of traditional filling pile has some disadvantages such as redundancy of data, difficulty in finding data, low working efficiency and poor timeliness. Thus, combined with the actual needs of filling pile construction management, based on the Java language, the mobile phone client of filling pile construction information management system was developed, and the mobile client system framework, operating process and functional framework were designed and illustrated. The software provided an advanced management method for the filling pile construction, it had great value to guarantee the construction progress and improve the information level of construction management.

The lateral wall deflection is the most intuitive parameter to reveal the stability and safety of underground excavations. The existing automated approaches, such as to serialize dozens of inclinometers along casing pipes, are too expensive to be applied in most common projects. To guarantee stable automation and lower the costs, a novel system based on strain measurement is proposed in this paper to achieve real-time automated monitoring of underground excavations. The specially designed components are highlighted to benefit the mass industrial production and rapid in situ assembly. By theoretical comparisons, the accuracy and resolution performance of the proposed strategy are demonstrated to be better than those of the traditional manual method. The applicability of the mentioned system was verified by an engineering case, from which it was demonstrated that the proposed system works well to predict the lateral wall deflection of underground excavations. The sensitivity of the monitored results to the boundary conditions is also carefully discussed. The designed system has broad application prospects to provide timely data for safety assessment to prevent the unexpected failure of underground excavation as well as other engineering structures with dangerous lateral deflection or movement.

At present, most of the domestic building safety inspection managements are completed by manual recording and photo evidence, these methods not only consume a lot of manpower and resources, but also have the disadvantages of low efficiency and high error rate. With the deepening application of computer and Internet technology in all walks of life, it provides an opportunity for information development of the safety inspection management as well as the improvement of management efficiency. The purpose of this paper is to design and develop a web-based safety inspection system. The system consists of mobile client software and cloud platform software. The mobile client is based on the Java language, it has the function of mobile client for security inspection management function, while the cloud platform adopts B/S structure and J2EE+SQL server mode, it is convenient to data storage and management. The researches of this paper have ameliorated manual and papery way of safety inspection. At the same time, by using of internet technology, the informatization level and management efficiency of production safety inspection has been improved.
