摘要
软土具有含水率高、强度低、可压缩性大、剪切性能差等不良工程特性,常常会引起建筑物或工程结构沉降、不均匀沉降、差异沉降等问题。文海水库软土厚度大于97m,为深入了解坝基土体情况,为深厚软基筑坝的设计和施工提供支撑,本文基于室内试验结果和现场勘察成果,对坝基软土物理力学特性进行了系统分析,揭示了文海水库大坝深厚软土地基的物理力学特性及分布规律,可为类似深厚软土工程积累研究经验。
Soft soil possesses unfavorable engineering characteristics such as high moisture content,low strength,significant compressibility,and poor shear performance,often resulting in issues such as building or engineering structure settlement,uneven settlement,and differential settlement.The thickness of soft soil in the Wenhai Reservoir exceeds 97m.In order to gain a deeper understanding of the soil conditions of the dam foundation and provide support for the design and construction of deep soft foundation dams,this paper conducts a systematic analysis of the physical and mechanical properties of the soft soil in the dam foundation based on indoor test results and on-site survey results,clarifying the physical and mechanical properties and distribution patterns of the deep soft soil foundation in Wenhai Reservoir Dam,and accumulating research experience for similar deep soft soil projects.
