本文研究的成果主要是论述一个通用的有限元法计算机程序,用于分析平面应变或轴对称的用土工布加固土壤连续介质的问题,同时也论述了在一系列直径为0.9～2.5米的圆桶内对铺有粒料运材道路进行的模拟试验。试验证明:用土工布加强是有效的,由于它能部分地减少车辙,从而改变了软粘土路基内的应力状态。通载形成深的车辙后,在荷载中心线下土工布加强系统中测得的垂直应力,平均为 Boussinesq 公式计算的83%左右,相当于无土工布系统应力的88%。在软粘土路基中其深度大约等于荷载作用的直径时,使用土工布加强路基
The research results of this paper mainly discuss a general-purpose finite element method computer program for analyzing plane strain or axisymmetric symmetry for reinforcing soil continuum media with geotextiles. It also discusses a series of circles with a diameter of 0.9-2.5 meters. Simulation tests on roads with pellets transported in barrels. Tests have proved that strengthening with geotextiles is effective because it can partially reduce the rut, thereby changing the stress state in the soft clay subgrade. After the deep rut passes through the load, the vertical stress measured in the geotextile reinforcement system under the load centerline averages about 83% of the Boussinesq formula, which is equivalent to 88% of the stress of the geotextile system. When the depth of soft clay subgrade is approximately equal to the diameter of the load, geotextiles are used to reinforce the subgrade.
