厦门机场路风化花岗岩旁压试验研究

旁压试验经过不断完善、发展、应用和推广，在与静力载荷试验、标准贯入试验等原位测试的比较中已凸显其优势，业已成为工程地质评价、地基承载力确定等实用可靠的方法。针对强风化花岗岩土体松散、土质较硬、取样和室内物理力学试验的困难，进行高压旁压器风化花岗岩原位测试，取得具有工程应用价值的成果，结果表明，虽然风化花岗岩由于受差异风化形成水平向不均匀性的影响，测试结果各指标间的相关性与黏土存在一定的差异，但黏土和风化花岗岩地基承载力随测点深度、变形模量与基床系数，地基承载力、变形模量和基床系数与标贯击数间均具有一定的线性相关关系，并对相关关系进行拟合，给出相应地拟合公式。

Application of pressuremeter test in hard weathered granite in Xiamen Airfield Road

Pressuremeter test has already become a practical, reliable method in geology project appraising, ground bearing capacity measuring through long time application, popularization, development and perfection. Its superiority had also been distinguished itself in the comparision between plate loading test, standard penetration test or other in-situ experiments. Aimed at the puzzles such as loosening, rigid, difficult in sampling and indoor phisico-mechanical testing in hard weathered granite, the high pressure pressuremeter tests are carried out; and some valuable results in engineering are obtained. Results indicate that there are some difference in the correlation of the test between clay and weathered granite because of the differential weathering in horizontal direction in weathered granite; but there also exist some linear relationships between the ground bearing capacity and the measuring point depth, deformation modulus and the bedding coefficient, ground bearing capacity, deformation modulus and bedding coefficient along with the number of standard penetration test. Fitting equations of linear fitting are provided.
