摘要
文章对滨河地区地下水位和地表沉降进行长期监测,在考虑土层变形的时间效应和不同特征土层间变形叠加的基础上,基于太沙基理论提出分段独立算法,并开发了考虑土体总应力变化和弹塑性变形的沉降计算程序,最后将计算结果与实测结果对比,吻合度较高;滨河地区地下水位下降与地表沉降存在正相关,水位升高对地表变形的影响具有滞后性,滞后性主要与黏土层特性相关。
The paper makes long-term monitoring of the underground water level and land subsidence in the riverside area, considering the time effect of soil deformation and different characteristics of soil deformation. Based on the Terzaghi theory, the segmentation independent algorithm is proposed, and the calculation program for the soil total stress settlement and elastoplastic deformation is developed. In the final part of the paper the calculation results are compared with the measured results, showing a higher degree of agreement. The underground water in riverside area is positively correlated with the soil surface subsidence, while water level rise has lagged features on the impact of soil surface deformation. The lagged features and characteristics of clay layer are related.
