Abstract：
This article is dedicated to investigating the properties of soil after its reinforcement with fiberglass elements through large-scale laboratory plate-load tests of various samples that varied in the numbers and lengths of the reinforcing elements. The investigation of the vertical elements considered the diameter increase at the bottom toe by using widening washers. The results were compared relative to each other and to the theoretical calculation results. The theoretical calculations for the settlements were undertaken based on the authors\' proposed method. The method considers the number, shape, area and material of the strengthening elements using a pre-proposed reinforcement area factor µ. This pre-established factor was calculated with reference to the elements\' geometry-the diameter of the vertical elements and the bottom\'s washer diameter-which determined the reinforcement area. A comparison between the reinforced and reference soft sandy soil samples indicated a 25% increase in the deformation modulus after the reinforcement process at a pressure of 25 kPa. Samples with µ ranging from 1.20 to 1.43 were 55-65% stiffer than samples with µ equal to 0.69 at a pressure of 100 kPa. The comparative analysis of the calculated results and the actual laboratory PLT test results was adequate for use for further development.
摘要：
本文致力于通过各种样品的大规模实验室板载荷测试，研究用玻璃纤维元件加固后土壤的特性，这些样品的数量和长度各不相同。垂直元素的研究认为，通过使用加宽的垫圈，底部脚趾的直径会增加。将结果相对于彼此并与理论计算结果进行比较。定居点的理论计算是根据作者提出的方法进行的。该方法考虑了数字，形状,使用预先建议的加固面积系数µ的加固元件的面积和材料。该预先建立的系数是根据元素的几何形状-垂直元素的直径和底部垫圈的直径-计算的，这决定了钢筋面积。加固和参考软砂土样品之间的比较表明，在25kPa的压力下进行加固处理后，变形模量增加了25％。在100kPa的压力下，µ为1.20至1.43的样品比µ等于0.69的样品的硬度高55-65％。计算结果和实际实验室PLT测试结果的比较分析足以用于进一步开发。
