摘要:
某跨海大桥为一悬索桥，其主塔位于海中的岛礁上。因岛礁山体略显单薄，受数条断层及其他构造裂隙的影响，整体完整性较差。在岩体结构模型概化的基础上，采用三维有限元数值分析方法，系统研究了山体边坡在塔基开挖，混凝土浇筑以及工程荷载作用下，岸坡岩体的应力、变形的分布特征和变化规律，为工程边坡稳定性和工程设计施工提供了基础资料和参考依据。
Abstract:
The main tower of a sea-crossing rope suspension bridge lies on an island. The thin mountain intersected by faults and other structural fissures result in low intactness of rock mass. Based on the simplified structure of rock, 3-D finite element modeling technique is used to analyze systematically the distribution of stress filed and strain filed in the rock mass of the engineering slope after excavation, pour and engineering load. The main results can be taken as the basic data and theoretical proofs to evaluate slope stability and guide correct excavation.
