针对浅埋海底隧道结构稳定性影响问题,依托深港西部通道深圳侧接线工程,采用非线性有限元法,选取10个典型断面,分析了强夯、堆载、未来建筑永久荷载等对浅埋海底隧道结构沉降与侧向位移的影响,探讨了影响的范围和作用强度。从而为未来填海区开发对浅埋海底隧道结构稳定性影响控制提供参考。
According to stability influence on the shallow tunnel structure, based on the Connecting Engineering of Shenzhen- Hong Kong Western Corridor Project at Shenzhen, ita settlement and lateral displacement influenced by dynamic compaction, heaped load and permanent building loads is analyzed by non-linear finite element, then the strength and scope of influence is discussed, which is provided as a reference for. the stability control of shallow tunnel structure influenced by the development in filled sea area.
