摘要
介绍利用工程类比法预估建筑物沉降及其分布规律的数值模拟计算方法。首先建立某区域地层的标准地层体系,然后根据建立的地层标准和标准地层划分方法将工程地层归一化为标准地层,再利用已建工程资料反演分析得到数值模拟计算参数,最后用得到的计算参数预估拟建工程沉降。以两个工程模拟计算结果和实际观测结果对照,说明这种模拟计算方法预估建筑工程沉降是有效的。
A numerical simulating method of forecasting the building settlements and its distribution characteristics using engineering analogy is introduced.A regional standard stratum system is established firstly;and then the project stratum is normalized according to the stratum standard established.The parameters for numerical simulation are obtained by inversion analysis.At last the settlements of new building can be predicted.The effectiveness of mothed is proved by comparing the simulation results with actual observation values in two projects.
