喷锚挂网结构在深基坑支护中的应用

The Application of Structure of Bolting and Shotcreting with wire Mesh to Deep Foundation pit Supporting

喷锚网作为支护基坑的一种新型支护形式,与其它支护方法相比,该方法由于其经济、可靠、施工便捷、变形小等显著优点,在我国岩土工程领域中已得到广泛应用。结合工程实例,分析了喷锚网支护作用机理和实际应用效果及其可行性。

Bolting and shotcreting mesh,as a new-type form for supporting Foundation pit,is characterized in a plurality of significant advantages：cost-efficiency , reliability , convenient construction,low deformation,etc.. ,which therefore has been widely applied in geotechnical engineering of the state.The paper aims to analyze the economic feasibility of theapplication structure of bolting and shotcreting with wire mesh to foundation pit supporting based on the analysis of the principle of thefunction of bolting and shotcreting mesh supporting and in combinationwith practical engineering examples.
