东洲大道工程边坡变形破坏机理分析

Analysis on Deformation and Failure Mechanism of Dongzhou Avenue Engineering Slope

东洲大道地处褶皱断裂复合部位,是典型人为扰动引起变形破坏的工程边坡。该文通过对处在褶皱转折端等特殊构造部位的边坡进行评价时,应适当扩大地面调查范围,同时加强岩体结构面及其特征的调查与统计,并充分考虑特殊工程地质水文地质条件,回溯验算不同工程阶段边坡的稳定状态,分析给出了二次变形破坏的机理。最后,对复杂地质结构体边坡的评价要点提出了结论与建议,可供同行参考借鉴。

Dongzhou Avenue is located at the compound part of fold and fracture, which is a typical engineering slope caused by human disturbance. In this article, through the evaluation of the slope at the fold turning end and other special structural parts, the ground investigation scope should be appropriately expanded, and the investigation and statistics of the rock mass structural plane and its characteristics should be strengthened. Taking full account of the special engineering geological and hydrogeological conditions, the stability of the slope at different engineering stages should be backtracked and checked, and the mechanism of secondary deformation and failure is analyzed and given. Finally, some conclusions and suggestions are put forward for the evaluation of slopes with complex geological structures, which can be used for reference by peers.
