Undermining Construction Technique Research On Dongwuyuan Subway Station Of Guangzhou City

In this paper, Guangzhou Metro Zoo station project, for example, described in detail subway station Subsurface application of construction technology and construction of important security specifications, at busy traffic junctions, construction of the station is very difficult to use Cut, transportation organizational difficulties, The tunneling method used to solve these problems. However, its technical difficulty and construction more difficult, economic indicators have also increased. Silty clay layer in Guangzhou, construction mining station to enhance precipitation, to ensure the station under construction in the water is particularly important. Through monitoring, feedback information, to guide the construction, to ensure that the construction carried out smoothly. Step 8 to complete this project with cross-channel cross-section of excavation, and then the gradual dismantling of temporary support to the completion of a four-step injection mold cross-channel cross-section of secondary lining. Every step of cross-channel construction, will be on the surrounding strata, on the surface building (structure) building materials, and even the stability of their own cause varying degrees of impact for the study of cross-channel caused by each step of construction of the mechanical behavior and stability, are the use of large-scale three-dimensional numerical analysis software FLAC3D, right cross channel to conduct the whole process of construction of three-dimensional dynamic numerical simulation to verify the designing and construction, to ensure the safety of the projects carried out smoothly for the construction unit of reference.
