高寒边坡岩体采动响应与多场耦合时效致灾过程研究高寒边坡岩体采动响应与多场耦合时效致灾过程研究

摘要

高寒边坡稳定性受多种因素影响，岩体内部的应力分布、温度变化、水分渗透和岩石结构破坏等都可能成为岩体破坏的诱因。本文针对高寒边坡岩体采动响应与多场耦合时效致灾过程进行了深入研究，主要内容包括：（1）提出高寒边坡岩体稳定性评价方法，并对不同因素的影响进行了分析；（2）通过数值模拟方法研究岩体内部应力分布、温度变化、水分渗透和岩石结构破坏等因素对岩体稳定性的影响；（3）应用多场耦合理论分析了采动对岩体稳定性的影响，并提出了相应的预防和治理措施。通过本研究，可以有效提高高寒边坡岩体承载能力，减少岩体破坏事故的发生，为区域经济发展和民生建设提供保障。
