等值梁法在深基坑支护设计中的应用

Application of the Equivalent Beam Method in Design of A Deep Pit

等值梁法是计算地下支护结构内力的经典方法。近几年来,尽管m法和有限元法日益受到国内外工程界的重视,但是m法基本上未考虑到土体的强度问题,有限元法在选定土体的计算模型、本构关系、计算参数等方面比较复杂,而等值梁法模型简单、便于计算、安全性高,所以在我国工程界有着广泛的应用。对某大厦基坑进行等值梁法的支护设计计算,可为类似工程的设计计算提供参考。

The equivalent beam method is one of the classic methods calculating the.internal force of underground support structure. In recent years, though the ＂m＂ method＂and the finite element method are paid more and more attention, the strength ot soil isn＇t considered in the ＂m＂ method, and it is very complicated in selecting the calculation model, constitutive relation and calculation parameters etc. in the finite element method. For the equivalent beam method, it is convenient and reliable tO select model and calculate, which has a wide range of applications. The support design of a buildings deep foundation pit is calculated by it, which is as a reference for similar engineering.
