摘要
为了了解土工织物补强重载软土路基的强度条件，笔者进行了土工织物补强软土的静力载荷试验和现场重载过车试验。根据试验结果，对于基本丧失承载能力的稀软土体，经土工织物补强后，依据土工织物的张力效应，可承受６００ｋＰａ的静载作用，由土工织物的张力效应和封闭作用所发挥的补强效果，其动载承受能力达到８００ｋＰａ。本文根据土工织物补强软土地基的基本原理，讨论了土工织物的主要功能及其补强效果，并对现场试验中出现的问题进行了原因分析。
In order to investigate the behaviour of reinforced soft roadbed of heavy-duty vehicle with geofabrics, two tests, namely static loading test and field vehicle loading test have been performed. The test results show that the soft soil mass, primarily losing its bearing capacity, has been reinforced with a static bearing capacity of 600 kPa due to the tensile effect of geofabrics, and with a dynamic bearing capacity of 800 kPa due to both tensile effect and control function of geofabrics. Based on the mechanism of the earth-reinforcement, the paper discusses the reinforcing functions of geofabrics and analyses the principal causes relative to some problems in the field test.
