建筑物移位工程位移控制临界值分析

Analysis of critical displacement in building moving project

采用基于区间分析的结构非概率可靠性模型,用超长方体集合定量建筑物移位(顶升平移)工程中结构所处的动态位移边界条件,提出了建筑物能承受的最大安全不同步度概念,并给出其分析的方法和步骤;定量了工程的可靠度,满足了液压同步控制系统安全控制的位移临界值的需要.

Based on the interval analysis of displacement boundary conditions, using hyper-rectangle set to the boundary conditions of a building in moving project. The conception of asynchronous gap of supporting points in moving direction was proposed. By using the optimal technique, the approach of computing the maximum safe asynchronous gap was presented, and the reliability of engineering was given. The results of analyses met the require- ments of critical position control of hydraulic synchrony control system.
