近日,由我院完成的《武汉市轨道交通2号线(街道口站~光谷广场站)隧道技术创新与实践》获得了2014年度湖北省优秀工程勘察设计一等奖。本区间隧道是武汉第一条采用矿山法施工的地铁隧道,地质条件复杂,岩溶发育,隧道埋深浅,地表建筑物密集,对地表沉降控制要求高,且武汉地区复杂地质条件下可借鉴的浅埋隧道设计与施工经验很少。为此,在开展了隧道工法研究、岩溶专题研究、卓刀泉保护等基础上,本项目进一步对岩溶处理技术、建筑物及重要文物保护方案、矿山法隧道信息化
Recently, the “Innovation and Practice of Tunnel Technology in Wuhan Metro Line 2 (Jiao Kokou Station ~ Guanggu Square Station)” completed by our institute won the first prize of 2014 Excellent Engineering Investigation and Design in Hubei Province. This interval tunnel is the first subway tunnel constructed by the mining method in Wuhan. It has complicated geological conditions, karst development, shallow depth of tunnel, dense surface buildings, high requirements on surface subsidence control, and shallow depth of reference for complicated geological conditions in Wuhan Buried tunnel design and construction experience rarely. To this end, based on the study of tunneling method, special research on karst and protection of Zhuodao spring, this project further analyzes the karst treatment technology, the protection plan of buildings and important cultural relics, the informationization of the tunnel of mine law
