研究了固化时间、纸张含量、固化温度、固化环境等因素对纸张质量的影响，试验研究了液化稳定土（LSS）的强度和变形特性。对现场养护28天和56天的土样进行了固结不排水三轴压缩试验和孔隙水测量。同时，探讨了便携式FWD试验在LSS掺纤维地基刚度评价中的适用性。试验结果表明，养护温度对掺纤维LSS的强度和变形性能的影响小于养护龄期的影响。此外，Kp. fwd值可以用来估算纤维增强LSS地基的刚度。
In this study, the influences of various factors, which are curing days, paper content, curing temperature and curing circumstance, etc., on strength and deformation property of Liquefied Stabilized Soil (LSS) prepared at field were investigated. A series of Consolidated–Undrained triaxial compression test with pore water measurement was carried out on the specimens cured in the field ground at 28 and 56 days. And also, the applicability on the evaluation of stiffness by portable FWD test at a backfilling ground by LSS mixed with fiber material is discussed. Base on the test results, it was found that the effect of curing temperature on the strength and deformation property of LSS mixed with fiber is smaller than the effect of the curing days. Moreover, the Kp.fwd-value is able to estimate the stiffness of backfilling ground by LSS reinforced with fiber.
