山顶建筑场地稳定性分析评价与边坡治理

在山顶建设大型建筑主要岩土工程问题是场地稳定性问题,本文通过某工程实例,分析了场地存在沿倾斜层面整体滑动、沿裂隙和层面局部滑动、块状风化岩覆盖层滑动、岩块崩塌及表层危岩、危石滚落等破坏型式,通过室内和现场剪切试验取得的结构面强度参数,对山顶边坡稳定性进行了常规方法和有限元法的定量评价,得出场地整体稳定性和局部稳定性满足要求的结论,对岩块崩塌和危岩危石滚落采取喷锚支护措施,本工程取得的经验对于类似工程具有指导意义。

STABILITY ANALYSIS OF BUILDING SITE OF THE PEAK AND SLOPE TREATMENT

Peak construction of large buildings in major geotechnical problems is the site stability problems,in this paper,an example of a site along the sloping level of the whole existence of sliding,sliding along the crack and local levels,covering layer of weathered rock block slide,rock collapse and surface rock,stone rolled down so dangerous form of damage,through laboratory and field tests to obtain the structural plane shear strength parameters,slope stability on the top of the conventional method and the finite element method for the quantitative assessment of the overall site stability obtained and meet the requirements of local stability of the conclusions of collapse and dangerous rock on the rock rolling stone risk taking shotcrete support measures,the experience gained in this project has a guide for similar projects.
