摘要
针对船闸改扩建工程施工中面临的边坡开挖陡、地质条件差异大、坡体变形控制要求严的问题,对邻近公路高陡边坡支护和稳定性进行研究。采用动态设计方法,对边坡开挖中揭露的岩层产状、发育节理组合情况等地质条件实时判断,结合边坡安全监测数据,提出不同破坏模式下的支护方式。结果表明:岩质高陡边坡动态设计在重要性特别高、范围广、地质和环境条件差异大的情况下具有针对性和适用性,能够实现工程安全、工程投资、施工进度等目标的综合效益最大化,相关经验和方法可为类似工程建设提供参考。
In view of the problems of steep slope excavation,large different geological conditions and strict slope deformation control,the support and stability of high and steep slope of adjacent highway are studied.By using dynamic design method,the geological conditions such as rock formation and joint combination revealed in slope excavation are judged in real time.Combined with the safety monitoring data of slope,the support methods under different failure modes are proposed.The results show that the dynamic design of high and steep rock slope has pertinence and applicability in the case of high importance,wide range and large differences in geological and environmental conditions.It can maximize the comprehensive benefits of engineering safety,project investment and construction schedule.The relevant experience and methods can provide reference for similar projects.
