摘要
在太原枢纽西南环线铁路改建隧道施工中,下穿环城高速采用CRD法易产生高速路面大幅沉降。本文通过对环城高速地面沉降、隧道拱顶下沉和水平净空收敛进行监控量测和数据分析,绘制环城高速地面沉降和拱顶下沉历时曲线并进行回归分析,提出相应的施工措施,为隧道施工提供科学依据。
The ground subsidence is enlarged in the inner ring expressway down traversing of tunnel construction with CRD when rebuil-ding the pivot southwest line of Taiyuan.This text draws duration curves and carries out regression analysis on inner ring expressway ground subsidence,tunnel arch top settlement and horizontal clearance convergence through monitoring measurements and data analy-ses,presenting reciprocal construction procedure and providing scientific grounds for tunnel construction.
