无锡市区土体工程地质层组划分及其应用
Division and application of engineering geological strata groups of soil mass in Wuxi City
摘要
Abstract
Wuxi City is located in the alluvial and lacustrine plain of the Taihu Lake,with thick quaternary loose sediments,where urban construction mostly takes soil as the carrier,and the quality of soil structure is related to the cost and cycle of engineering construction.However,for a long time,there has been no unified standard for the division of soil mass engineering geological strata in Wuxi city,and the stratum coding is confused,which seriously reduces the reusability of engineering geological data.In order to improve the universality of engineering geological data and maximize its utilization value,based on a large amount of geological drilling and soil parameter testing data etc.,this article establishes stratigraphic sequence structure and coding rules through drawing engineering geological sections.The soil mass within a depth of 100 m in Wuxi is divided into 9 engineering geo-logical strata groups and 27 engineering geological layers.The rationality and correctness of this engineering geological strata group division scheme has been proved through the discrete characteristics of soil parameters and the 3D geological structure model.The result is widely used in the selection of pile foundation bearing layer,evaluation of suitability for underground space development and utilization,and shallow geothermal energy development.The result also has guiding significance for engineering investigation,urban planning,construction and management,and major project site selection in Wuxi City.关键词
