基于功能原理的南宁膨胀土竖向膨胀能研究
摘要:基于改进的室内膨胀能测定实验,联合静力压入法的试样制作新方法,以功能原理为出发点,从能量的角度对南宁膨胀土的膨胀能进行了试验研究和理论分析,探讨了南宁膨胀土的静力压实功和膨胀释放能与含水量、干密度之间的关系。试验表明,膨胀能和压实功均与初始含水率近似成线性反比关系,与干密度成线性正比关系;干密度是影响压实功和膨胀能的主要因素。
Abstract:Based on ameliorative experiment about swelling energy measurement of Nanning expansive soils, new technique of making soil samples and principle of work-energy, experimental investigation and theoretical derivation are done from the perspective of the energy. The relationship between Nanning expansive soils" swelling potential and initial water content, initial dry density are discussed. Test shows that static force compacting work and swelling released energy are all inversely related to initial water content. There are rectilinear relationships between compacting work, swelling energy and density. Moreover, density is the main influential factor of compacting work and swelling energy.
