《南水北调与水利科技》：地锚地下连续墙在水利工程建设中的应用（王文红）（摘要）

摘要：在水利工程建设中，为不影响邻近建筑物的安全或使相邻新建结构物基础落在原状土上，不致发生较大的不均匀沉降，影响建筑物的安全，常常需在深基坑开挖中采用适当的临时支护结构，以保护邻近建筑物的地基稳定。地锚地下连续墙是一种新型的基坑支护体系，近几年广泛应用于城市高层建筑的深基坑支护中，但在江苏省水利工程中尚不多见，南水北调东线第一期工程淮安四站泵站工程深基坑首次采用压力分散型预应力锚索地下连续墙进行支护，获得了成功。

Abstract:During the construction of water conservancy projects,in order not to affect the security of adjacent constructions or make the groundwork of the adjacent new structures fell over the undisturbed soil,and not to render big non-uniform settlement,which affect the security of the structures,proper temporary support structure are often adopted in the excavation of deep foundation trench,which shields the stabilization of the structures in the vicinity.Anchor block underground diaphragm wall is a sort of new foundation trench support system ,which is extensively uesd in the deep foundation trench support of high-rise buildings in the city.However,it""s not commonly adopted in water conservancy projects in Jiangsu Province.Pre-stressed anchor underground diaphragm wall of pressure dispersion type is firstly adopted for support in the deep foundation trench of Huaian-Ⅳ-pumping station in the east route of South-to-North Water Diversion project and obtained great success.

Key words:anchor block;undergorund diaphragm wall;water conservancy projects;application
