The methods of bridge foundation position determining and stability analysis of slope based on mechanical behavior of rock mass are put forward. And the present design theory is improved.
本论文对高陡边坡岩体在荷载作用下的力学行为特征进行系统的分析,揭示荷载作用下边坡岩体力学行为特征及变化规律,提出基于岩体力学行为分析的高边坡桥基位置设计及边坡稳定性分析方法,补充完善现有设计理论。
The monitoring data shows that at present most subgrade deformation is not more than 2cm in frozen earth zone, the bridge foundation deformation all satisfy the design requirement and the engineering buildings in permafrost zone are basically stable.
观测数据表明,目前冻土区工程绝大部分路基变形不超过2cm,桥梁基础变形全部满足设计要求,冻土区工程建筑物基本稳定。
