HP-1护坡浆液固化黄土的抗压强度和渗透性试验

摘要

为了研究 HP-1护坡浆液加固黄土的效果和最佳配比,采用正交试验方法,对影响加固土的力学性能和渗透性的因素(P-2、Z-1、Z-2掺量)进行了无侧限抗压强度试验和渗透试验.结果表明:HP-1护坡浆液大大提高了黄土的无侧限抗压强度,降低了黄土的渗透性;HP-1护坡浆液最佳配比为P-2、Z-1、Z-2掺量分别为0.04%、5.0% 和0.20%;湿加固土抗压强度最大,渗透系数最小,是最佳的配制方式.%To study the effect and optimal ratio of HP-1 slope protection slurry for solidified loess,the unconfined compressive strength test and permeability test of the influence factor(P-2 content,Z-1 content and Z-2 content)on mechanical properties and permeability of solidified soil have been carried out using the orthogonal test method.The test results show that HP-1 slope pro-tection slurry greatly improves the unconfined compressive strength of soil and reduces the permeability of soil.The optimum ra-tio is 0.04% P-2,5% Z-1,and 0.2% Z-2.Wet solidified soil has the highest compressive strength and the minimum permeability coefficient.It is the best preparation method.
