| 摘 要： | 立足于土体演化的地质背景，以湛江地区第四系下更新统湛江组强结构性软土地层为依托，开展了宏观与微观土工试验研究，探求该区软土赋存规律与其强结构性的内在联系。研究表明，湛江软土是以陆相沉积为主的河控三角洲相(即海陆交互相)沉积层，由于受该区构造运动的强烈影响，该土集多种地质营力的复杂耦合作用而呈现出特殊的沉积特征；胶结作用是该土具有较高的结构强度的根本原因，其强结构性形成机理与当地广泛发育的红土极为相似。

| Abstract: | Based upon geologic background of solum evolvement, aimed to strong structural soft clay strata Zhanjiang Formation lower Pleistocene series the Quaternary system in Zhanjiang area, the research on soil properties, which combines macroscopical mechanics test and microanalysis, has been made, so as to disclose internal relations between occurrence and strong structural characteristic of soft clay in this area. It is shown that Zhanjiang Formation is the deltaic-facies strata controlled by river(interactive marine & continental sedimentation); and its special sedimentation characteristic result from multi-geologic-agent coupling action with strong tectonic movement working on. Fundamentally, agglutination among particles result in the characteristic strong structural strength of this soft clay, and its pedogenic mechanism is extraordinarily similar to that of indigenous laterite. |
