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 understand the strength conditions of geotextiles for reinforcing soft soil subgrade, the author carried out static load test and on-site overloading test of geotextile-reinforced soft soil. According to the test results, for dilute soft soils with loss of carrying capacity basically, after geotextile reinforcement, according to the tension effect of geotextile, it can withstand the static load of 600kPa, which is exerted by the tension effect and the closing effect of geotextile Strong effect, its dynamic load capacity to 800kPa. According to the basic principle of geotextile reinforcing soft soil foundation, this paper discusses the main function of geotextile and its reinforcement effect, and analyzes the causes of the problems in the field test.
