码头岸坡土体相关距离的求解

Solution of soil's correlation distance of wharf bank slope

码头岸坡多为天然土层沉积而成,土体参数具有空间变异性,应用随机场理论可以实现土性参数的点变异性到空间变异性的转化。土性参数随机场是一个平稳随机场,相关距离是描述土性参数随机场的一个重要指标。基于随机场理论,利用静力触探曲线数据按相关函数法拟合求解了码头岸坡土体的相关距离,为今后开展码头岸坡的可靠度研究打下基础。

Wharf slopes are often formed by the natural soil sedimentation. Soil parameters are space- variable, and the soil localized point variability can be changed to spatial variability based on the random field theory. The soil character random field is a stationary random field, and correlation distance is an important parameter which can reflect characteristics of the field. Based on the random field theory, CPT data has been used, then according to the relevant function method, the correlation distance of wharves soil is fitted and solved, and the work lays a foundation for the reliability study on the wharf slopes.
