摘要
本文对某过街隧道施工开挖方法进行研究,主要提出了两种隧道开挖方法:一种是中导洞+CRD法;一种是中导洞+CD法。并采用三维有限元模型对隧道两种开挖方式进行了数值模拟分析,通过沉降位移控制和应力控制计算分析得出,中导洞+CRD法和中导洞+CD法各有优劣,需要根据工程情况、地质条件及施工条件来进行选择。
This paper put forward two kinds of tunnel excavation methods, one is middle drift＋ CRD, and the other one is middle drift＋ CD, and three dimensional finite element model was used to simulate the two exca-vation methods, and obtained the settlement displacement and stress control values. The middle drift ＋ CRD and the middle drift ＋ CD have their own advantages and disadvantages. Regardless of the method used, ac-cording to the engineering condition, geological condition and construction condition, the choice was made.
