| 摘 要： | 为了在沙漠地基勘察中推广应用静力触探技术，在控制相对密度和含水量的条件下，进行了一系列室内大、中型槽原位测试模拟试验及相关土工试验，取得了塔克拉玛干沙漠砂静力触探指标 ，标准贯入试验锤击数 和抗剪强度指标 的一系列有效数对，并进行了线性回归，建立了 - 和N- 之间的相关关系，且论证了二者之间的协调性。给出的公式为沙漠油田地面工程勘察积累了经验。

| Abstract: | In order to apply and disseminate static cone penetration test(CPT) technology in desert investigation, a series of in-situ stimulated test and soil engineering test are carried out in big trough and medium trough under the condition of controlling relative density and moisture content in laboratory. And some indexes of Taklamakan desert sand, such as static point resistance , standard penetration test(SPT) blow count N, angle of internal friction etc. are obtained at the same time. Through analysis and linear regression, it gives two equations of - and N- and their coordination. All these are accumulated experience for ground engineering investigation of desert oil field.. |
