塔克拉玛干沙漠砂静力触探试验研究

在控制相对密度和含水量的条件下进行了系列室内大型槽和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锥尖阻力qc与容许承载力pa、内摩擦角? 、相对密度Dr和变形模量E0.01的一系列有效数对，建立了qc- pa，qc-? ，qc-Dr，qc-E0.01等相关关系，并给出了适合在沙漠地区应用的数字化表格，为在沙漠地基勘察中推广应用静力触探技术积累了经验。

Testing research of cone penetration test on Taklamaka desert sand

A series of in-situ simulated tests and geotechnical tests are completed in big trough and medium trough under the condition of controlling the relative density and moisture of the Taklamaka desert sand in laboratory. Then some data and indexes such as static point resistance qc of cone penetration test, allowable bearing capacity pa , angle of internal friction ? , relative density Dr , modulus of deformation E0.01 etc. are got. On the basis of these data, some correlations including qc vs. pa , qc vs.? , qc vs. Dr , qc vs.E0.01 and digital forms applied for desert are given. All these are accumulated experience for application of cone penetration test on desert foundation investigation.
