Abstract: With the underground spaces development, there are increasing numbers of deep foundation pit engineering problems emerged in the process of the urban construction. Especially in some coastal economically developed city, deep foundation pit in soft soil area has become a high risky project. Many scholars have carried out some researches on the effect of foundation fit excavation on existing...
Abstract: Earth pressure balance shield is widely used in recent years for safety and high efficiency in the process of urban subway construction. However, there are some problems in the engineering application. For example, the ground response of excavation face is one of the major problems, which affect the security and stability of adjacent buildings and other structures. The problem of excavation...
Abstract: With rapid development of underground rail transport in China, effect of foundation pit excavation on underlaid metro tunnel has been increasingly concerned since the 21st century. The excavation inevitably leads to the upheaval of the tunnel. If the deformation values of tunnel exceed their allowable values, the safe performance of tunnel will be affected. Many scholars carried out some...
