我国湿陷性黄土分布广泛,鉴于湿陷性黄土的特殊性和复杂性,黄土场地的湿陷类型及地基湿陷等级是湿陷性黄土地基处理前必须要准确查明的关键问题。按规范进行自重湿陷量的计算时,其修正系数因地区土质而异。本文通过分析某浸水试验场地不同深度的湿陷变形量的变化规律,揭示了地层湿陷系数随深度的变化规律以及地层岩性对浸水湿陷变形的影响,为该湿陷性场地评价提供指导性意见。
Because of the particularity and complexity of collapsible loess, the collapsible loess type and the collapsible level of the loess are the key problems that must be accurately identified before the collapsible loess foundation is treated. According to the specifications for self-weight calculation of the amount of collapse, the correction factor varies according to the region soil. In this paper, by analyzing the law of deformation of collapsible deformation at different depths in a water immersion test site, the variation law of the collapsibility coefficient of the formation with depth and the influence of formation lithology on the deformation of the water immersion are revealed to provide guidance for the evaluation of the collapsible site Sexual opinions.
