摘要
为研究土工格栅对公路软土路基变形影响的工作性状,依托山西某高速公路工程,采用土工格栅和土工布作为不同加筋材料与非加筋土进行试验路施工及工后监测。结果表明,相对无筋土,土工格栅降低软土路基的沉降位移最大值可达11%,侧向位移值减小约51%;加筋材料的不同对变形的发展也有差异;同时,土工格栅有利于路基断面均匀受力,提高路基稳定性。
To research the working performance of the geogrids on soft foundation, a test of engineer- ing in field has been made. The test includes the construction and monitoring of the reinforced sub- grade and the common subgrade. The results show that the application of the reinforced composite has a significant effect on constraining the horizontal and vertical displacement of soft foundation. The maximum displacement of the subgrade is about 11%, and the lateral displacement value is about 51%. The deformation of soft foundation will be different if different material is used in subgrade. The use of the grids is also helpful for the stressed uniformly of the subgrade section.
