洞桩法施工车站地表沉降的有限差分法分析

Finite-differfence analysis appliance to shallow buried under ground excavated tunnels with the cavern-pile method

针对光华路地铁中洞的大断面,拟采用洞桩法进行施工,并应用有限差分法对洞室拱顶及地表的沉降进行了模拟,得出的预测沉降规律为施工工作提供了指导。

In the project of Guang hua Road Subway ,to aim directly at the big size in the middle hole, the author plan to use the cavern-pile method and use 3D finite-Difference analysis to simulate the displacement at the top of the hole and the ground displacement. Then use the data to predict the regularity of the displacement and to direct construction.
