摘要
本文根据影响土工参数不确定性的主要因素建立起来的随机模型,探讨了土工参数不确定性的一种计算途径。对土的空间平均特性问题,根据土性随机场理论,就波动幅度(相关距离)的计算提出了曲线极限法。并获得了土工参数空间变异系数的综合计算式。
Based on the probabilistic medol relating to the main sources affecting uncertainties of soil propeies,amethod which may be used to evaluate the uncertainties is discussed。For the spatial average soil property,a curve-function method is put forward to compute the scale of fluctuation(correlation distance)according to the randomfield theory theory of soil piofiles.Then a synthetical formula is established to calculate the coefficient of spatial variation.
