摘要
为了验证某工程复杂地质条件下的表孔溢洪洞进口边坡设计支护方案的可靠性和合理性,通过有限元MIDAS软件的强度折减法对边坡在不同运行工况下进行边坡稳定性分析,边坡安全系数的计算结果均符合规程规范的要求,计算结果表明该设计方案合理可行,边坡整体稳定,为设计及施工提供了依据。
In order to verify the reliability and rationality of the design support scheme of the entrance slope of the surface spillway tunnel under the complex geological conditions of a project,the strength reduction method of the finite element midas software is used to analyze the slope stability under different operating conditions,and the calculation results of the safety factor of the slope meet the requirements of the codes and regulations.The calculation results show that the design scheme is reasonable and feasible and the slope is stable as a whole.It provides a basis for design and construction.
