Abstract:
The foundation pit dewatering of subway station during excavation is an important part of the work progress.However, the job location of the subway station is generally located in the region of high population flow, and the foundation pit dewatering always brings some bad influence on the surroundings.So the foundation pit dewatering should be studied and analyzed.Based on a metro station of Line No.6 of Wuhan Metro, this paper explains the change law of surrounding building settlement and deformation of retaining structures by using the practical nonitoring data during the process of foundation pit dewatering.Main conclusions are as below:1) in terms of the influence of surrounding buildings, the effect of external foundation pit dewatering is much bigger than that of internal foundation pit dewatering; 2) the effect of external foundation pit dewatering can reduce the active earth pressure of the foundation pit lateral in some degree, and then reduce deformation of retaining structures; 3) the soil property and condition of foundation pit dewatering would have a great impact on the deformation of retaining structures.

Abstract:
Design is a process of continuous development and intensification, in which originality and form mix and collide with each other constantly, and ultimately reach a balance. This is also the reflection of the quality of design. Efficiency and quality have different emphases at different stages of design. At the initial stage, a great deal of information needs to be collected and integrated to reach a conclusion. By reasonable and goal-directed collection, effective cooperation, independent and concentrated thinking, and data organization, high efficiency is realized. At the stage of intensification. the dynamic integration of "form" and "connotation" is emphasized. Based on accumulation and summary as well as personalized analysis of the form and connotation and by virtue of diversified methods of looking for the connotation, intuitive paths of thinking are put forward. Furthermore, timely communication among the participants in the plan can be guaranteed through a perfect cooperative system. This can guarantee the quality and enhance the efficiency simultaneously. Although a good method can improve the efficiency of design, it still cannot change the essence of design. Only by learning, practicing and thinking continuously can one design excellent works.

Abstract:
The traditional plywood can't shape space concrete structure, and therefore, this article puts forward the concrete construction technology for 3D curved cantilever structure. This construction technology uses the supporting system of "steel plate" plus "steel keel" to prevent deformation during construction, uses steel plate cutting and assembly techniques to solve the problems of irregular changes in the surface normal direction, and uses computer 3D modeling to carry out detailed design and sample processing for the structural steel keel, which makes T-shaped steel keel structure accurately simulate the irregular changes in the longitudinal direction. Making full use of the drainage hole of the structure itself to enhance the whole modeling supporting system, this technology guarantees that the structural curve keeps smooth to meet the high standards of concrete appearances.
