PVC纤维土三轴试验分析

Triaxial Test of PVC Texsol Analysis

采用三轴仪对PVC纤维土在固结不排水的条件下,进行常规三轴压缩试验,探讨在不同长度或掺量组合下该纤维土的应力-应变关系,分析影响纤维土应力-应变关系及其抗剪强度的因素.试验结果表明,该纤维土的抗剪强度较没有掺加纤维的素土有提高,说明纤维对土体存在补强的作用;同时,试验得出粘聚力是影响纤维土抗剪强度的主要因素.

The triaxial experiment instrument is used to carry on the triaxial compressive test,under the condition of PVC texsol in solidifying and not draining water.The textile fiber earth stress-strain relations in the different length or mixes under the quantity combination are discussed,and the factors of influencing texsol stress-strain relations and shearing strength are analysed.The test result indicats that this textile fiber earth＇s shearing strength has not spiked the textile fiber the element earth to have the enhancement,which shows textile fiber can reinforce the soil body existence.At the same time,the experiment obtains that the cohesive force affects is the primary factor of the textile fiber earth shearing strength.
