望基湖停车场断裂构造对隧道施工的影响

Influence of fracture structure of Wangjihu parking lot on tunnel construction

以深圳地铁8号线8133标出入线隧道初支开挖为例,从地质断裂构造对隧道开挖施工的影响进行分析,阐述断裂构造在隧道开挖过程中引起的常见次生地质灾害及其原因,并通过采取地勘、监控量测、提前支护等手段,减少不良地质构造对隧道开挖带来的不利影响。

This paper takes the initial branch excavation of the entrance tunnel marked with 8133 of Shenzhen Metro Line 8 as an example.From the impact of geological fault structure on tunnel excavation construction,explaining the common secondary geological disasters caused by fault structures during tunnel excavation,and through the use of geological survey,monitoring and measurement,early support and other means to reduce the adverse impact of bad geology on tunnel excavation.
