摘要

地表沉降的研究工作大都集中在地铁隧道盾构法施工的情况，而对于矿山法城市双连拱隧道施工引起地表沉降的研究几乎没有。本文以重庆彭家花园双连拱隧道为工程背景，就矿山法双连拱隧道施工引起的地表变形进行研究。在不同施工方法条件下，针对不同埋深、断面大小进行回归分析，从理论上弄清地表沉降的规律，根据实测资料，提出矿山法施工条件下地表沉降的预测公式。并结合三维数值模拟验证了回归效果

Abstract

The study work of surface subsidence has been mostly focused on shield construction of underground tunnel

while there has hardly been any research on surface subsidence caused by mining method constructing city double-arch tunnel. Based on the double-arch tunnel in Pengjia Garden

the study of surface subsidence caused by mining method construction has been carried on. Under the conditions of different construction methods

the regression analysis pointed to different depths of embedment

different section areas is used

so that the law of surface subsidence is obtained in theory; according to the monitored data

a forecast formula of surface subsidence under mining method is put forward. The regression effect has been validated combining with three dimensional numerical simulation
