Pile-anchor Supporting Design And Finite Element Mothod Of Deep Excavation On Kunming City

This paper based on. the hot spots which are concerned by geotechnique,and systematically expounded the present situation of the shoring of deep trench,then analysed the importance of the shoring of trench.The paper took a project in Kunming as an example .adopted FEM to analyse the basic theory of the support of pile-anchor and generalized the designing ideas.Besides this paper emphasized several points as follow,which mainly focus on the major characteristic of supporting design,and reasonably choosed designing parameters and supporting program as starting point,and then combined with the local conditions.1. expound the technological development, principle for design and applied conditions of the shoring of deep trench.2. generalize the classifications and design methods of the shoring of trench.3. introduce the FEM for the shoring structure.4. design the shoring of trench in Kunming ,and analyse it with FEM.In the paper, it can finally come to the conclusion that the supporting program of pile-anchor is practical ,economic ,and safe in Kunming after the designation and analysis of the project in Kunming .So this paper might have some applied value in conducting foundation engineering in Kunming.
