在郑州—西安客运专线通过的关中东部某地进行的自重湿陷性黄土场地现场浸水试验中,采用浅标点和深标点对地基土地面湿陷变形及深层湿陷变形进行了观测。该文根据实测数据对自重湿陷的发生过程进行了分析,并将现场实测结果与室内土工试验计算结果进行了对比,对比结果表明试验场地实测自重湿陷量的结果与以往对“关中地区”黄土的认识存在较大差异。该文的研究成果可供今后类似工程场地自重湿陷性评价及修订黄土规范参考。
In the in-situ immersion test of self-weight collapsible loess site in the eastern part of Guanzhong through the Zhengzhou-Xi’an Passenger Dedicated Line, the deformation of the ground-surface collapsible soil and the deformation of the deep collapsible soil were observed with shallow punctuation and deep punctuation. According to the measured data, the process of self-weight collapse is analyzed, and the field test results are compared with the results of indoor geotechnical test. The comparison results show that the measured self-weight collapsing results at the test site are similar to those of previous “ ”Loess understanding there is a big difference. The research results of the paper are available for future evaluation of collapsible and self-weight collapsible engineering sites and revision of loess specifications.
