目前载荷试验是按现行工程地质勘察规范(TJ21-77)规定的加荷、观测标准(即相对沉降稳定法)进行的,每作一个试验一般需要3～5天,甚至更长时间,因此一般不轻易采用这种方法。原建工部综合勘察院于1962年曾提出过载荷试验的快速法,但长期以来未被广大勘察单位所重视。一些采用过快速法的单位,则认为快速法比相对沉降稳定法有较多的优 The current load test is carried out according to the current loading and observation standards specified in the current Engineering Geological Survey Specification (TJ21-77) (ie, the relative settlement stability method). Each test usually takes 3 to 5 days or even longer, so it is generally It is not easy to use this method. The Comprehensive Survey Institute of the former Ministry of Construction and Industry issued a rapid test of load tests in 1962, but it has not been taken seriously by the surveying agencies for a long time. Some units that have used the rapid method believe that the fast method has more advantages than the relative settlement stability method.
