军民一级泵站软岩工程地质特性研究

摘要

软岩工程因其易风化、软化等特性，通常引起地基强度衰减、不均匀沉降以及边坡失稳等工程地质问题。依托于军民一级泵站拆建的工程实例，通过分析地质资料，综合比较基岩承载力特征值确定方法，针对白垩系泥质粉砂岩地基进行了相关工程地质问题研究，提出相应的工程处理措施建议，为类似工程设计、施工提供了参考依据。%Soft rock engineering because of its special geological conditions ,usually accompanied by rock weathering ,wa-ter softening and slope stability and other engineering geological problems .Based on the Junmin pumping station demoli-tion construction engineering example ,through the analysis of geological survey data and the comprehensive comparison of bedrock bearing force characteristic value determination method ,the paper carries on geological research for Cretaceous argillaceous siltstone foundation ,puts forward the corresponding engineering treatment measures and suggestions ,provides the reference for similar engineering design and construction .
