COMPARISON BETWEEN PROBABILITY PREDICTING AND ACTUAL MEASUREMENT OF SETTLEMENT OF TANK FOUNDATION
-
摘要: 应用可靠性理论,利用软土地基土性指标的统计数据,对油罐地基的沉降进行概率分析,得到了可能的沉降区间;并与根据沉降实测资料应用双曲线法推算得到的地基最终沉降量进行了比较。由实测推算的最终沉降均落在预计区间之内。Abstract: Using reliability theory and statistic data on soil indexes of soft foundation, a probability analysis of settlement of tank foundation is done and the settlement confines are obtained, which are compared with the final settlement gained on the basis of measured data with hyperbola method. The final settlement is within the confines of predicted field.
