摘要
在岩土工程施工中对酸碱污染地的基土进行承载力学分析和受力检测,为指导岩土工程施工的开凿深度、混凝土配比等提供数据参考。提出基于刚度软化传递力学分析的岩土工程施工中酸碱污染地基土检测方法。构建酸碱污染地基土的本构力学分析模型,根据等效弹性应力和屈服强度关系计算酸碱污染地基土的延性力学参量,根据基土的承载力徐变关系得到酸碱污染地基土的承载屈服分布模型,实现酸碱污染地基土检测的力学检测。
In order to guide the excavation depth of geotechnical engineering, the bearing capacity of the-alkali contaminated area is analyzed and the force is tested in geotechnical engineering construction. tening transfer mechanics analysis, this paper puts forward the testing method of acid - alkali contaminated foundation soil ingeotechnical engineerng construction , and constructs the constitutive mechanics analysis model of acid - alkali contaminated foun-dation soil. According to the relationship bet-ween equivalent elastic stress and yield strength , the ductile mechanical parameters of acid - alkali contaminated foundation soil are calculated. According to the bearing capacity creep relationship of basic soil , theload - bearng yield distribution model of acid - alkali contaminated foundation soil is obtained.
