隧道施工引起地表沉降的Peck公式预测概述

大量高速公路和城市地铁的新建带来许多隧道施工引起地表沉降问题,Peck公式是预测隧道施工引起地表沉降最广泛的经验方法。文章通过对国内外隧道施工引起地表沉降Peck公式的研究成果进行归纳总结,包括Peck公式理论、Peck公式改进预测方法(地表纵向沉降和深层土体沉降)和Peck公式参数(地层损失率和沉降槽宽度)等方面,以期总结成果能为Peck公式在高速公路和城市地铁隧道工程方面的应用和研究提供参考。

Summary of Peck Formula Prediction of Ground Subsidence Caused by Tunnel Construction

A large number of new expressways and urban subways bring many problems of surface settlement caused by tunnel construction.Peck formula is the most widely used empirical method to predict the surface settlement caused by tunnel construction.This paper summarizes the research results of Peck formula for surface settlement caused by tunnel construction at home and abroad,including the theory of Peck formula,the improved prediction method of Peck formula(surface longitudinal settlement and deep soil settlement)and the parameters of Peck formula(formation loss rate and settlement groove width),etc.,so as to summarize the results can provide a reference for the application and research of the Peck formula in highways and urban subway tunnel engineering.
