摘要

结合武汉某深基坑支护工程，介绍了加筋水泥土墙复合土钉这一新型支护形式。通过对加筋水泥土和土钉的应力、位移进行测试和分析，研究了加筋水泥土墙复合土钉支护的工作机理。主要结论为：(1)支护变形特点为上大下小。(2)在一定的应力水平下水泥土和加筋体可以共同工作。(3)加筋水泥土墙在施工过程中起重要支挡作用。(4)支护结构的工作机理主要为挡墙效应、加筋效应和锚固效应。

Abstract

A kind of new composite soil nailing with reinforced cemented-soil wall is described and applied in a foundation excavation project in wuhan. A field investigation with extensive instrumentation and data collection is carried out

then the behaviors of the new composite soil nailing are further investigated based on the measurement. The main results are：(1) the defection is large at the top and little at the bottom; (2) cemented soil and reinforcing bar can work together at some level of stress; (3) the reinforced cemented-soil wall plays an important role during construction; (4) the behaviors of this supporting system include retaining-wall effect

reinforcing effect and anchor effect.
