摘要
以拟建的广州地铁5号线(草暖公园站———小北站)盾构区间工程为例,介绍盾构穿越岩溶段时的施工工序流程和常用的超前地质预报手段。鉴于目前各种地质预报手段的局限性,应在设计阶段加强地质调查和勘察工作,施工前还应有针对性的详细补充勘察,以求地质预报资料的准确性。探讨了穿越岩溶的施工预处理技术以及盾构在穿越溶洞段时的相应措施。
Based on the proposed shield tunneling section between Caonuan Park Station and Xiaobei Station of Guangzhou Metro Line 5, this paper introduces the construction process and the method of geology forecast,which is commonly adopted in metro construction when shield machine is driving in the karst section, and discusses the pretreatment methods and corresponding measures in such cases.
