摘要
Abstract
The Shizishan Tunnel in the Dali section of the Central Yunnan Water Diversion Project is located in the red bed soft rock section with prominent deformation.In order to facilitate the construction of an ultra-long water conveyance tunnel,an inclined shaft has been set up as a construction adit.The structural span at the intersection of the adit and the main tunnel is large,making it difficult to control deformation and stability during excavation and support.This article explains deformation control measures taken based on the specific conditions,such as zoning and blocking,excavation procedures,and supporting structures at the intersection of the adit and the main tunnel,which can provide reference for the construction of similar projects.关键词
