| 摘 要： | 上海地区桩基工程勘探中忽视桩端主要持力层范围内相对软弱夹层存在的情况时有出现。文章从第四纪地质角度分析了相关地层组成复杂性的客观因素,它是松散土层垂直相变的反映。同时指出,当前工程勘察工作中现场勘探劳务施工和岩土工程工作脱离、岩土工程师缺乏第四纪地质观念,常以建筑材料观念看待、处理地基土层,以及过分依赖计算机的倾向。建议按ISO9001精神,加强桩基勘探工作的全过程控制。

| Abstract: | It always appears that the soft interlayers in the chief pile-end's compression strata to be neglected at geotechnical investigation in shanghai.In this paper,deposit of the complicated Pile-end soil layers is analyzed from the quaternary geological perspective, it was the result of the sedimentary vertical phase transition.Also pointed out that,Current engineering survey work in the field exploration and geotechnical engineering services are separated,geotechnical engineers often view and process the found... |
