摘要
广州地铁隧道以盾构施工为主,在岩溶发育地段施工存在较大的安全隐患,容易使盾构机下部土体不稳定而塌陷,导致突水、突泥和盾构机具陷落等事故,从而引发严重的安全事故,后续处理非常困难。在岩溶地区兴建地铁隧道工程尤其应进行专门的基础处理,文中介绍广州地铁五号线草暖公园至小北站盾构隧道溶洞处理实例并进行分析研究。
Guangzhou metro tunnel to shield construction,in karst development area,easy causing instability and collapse,mud and water shield machine falls wait for an accident,the shield machine at once will have serious accidents and subsequent processing is very difficult.In the karst area construction,due to dissolve hole with great difficulty,cost is high,based on guangzhou metro line 5 of shield tunnel karst processing as engineering examples are analyzed and studied,the follow-up of rail transit line will encounter such dissolution hole processing design and construction of practical and guiding role.
