【摘要】 边坡开挖变形规律对开挖稳定性影响很大,特别是破碎岩质边坡。本文结合万粱高速公路张家坪路堑高边坡工程,开展了地质力学模型试验研究。研究了仅开挖不加支挡结构和先加支挡结构后开挖两种工况下,边坡开挖的变形规律,本项成果对设计和施工提供了有价值的参考资料。更多还原

【Abstract】 The regulation of slope excavation has a large influence on excavation stability, especially fracturerock slope. According to the Zhangjiaping high cut slope of Wanliang Highway, We proceed the geomechanicsmodel test. Analyze the regulation of deformation during slope excavation, under such two conditions: onlyexcavate without structure and excavate with structure done. This result provides worthy reference to design andconstruction.更多还原
