摘要
通过对西安静压PHC管桩静载荷试验资料分析,依据Q-S曲线得到单桩竖向极限承载力,采用数理统计的方法对单桩竖向极限承载力与终压力的关系进行回归分析,分别建立了以粘性土和砂土为持力层时,摩擦型和端承型静压管桩终压力与单桩竖向极限承载力关系的地区经验公式,对今后类似工程的设计和施工提供参考,对西安静压管桩的进一步推广和应用提供依据。
According to analysing and studying on the materials of Xi＇ an static pressing PHC pipe pile static loading test and Q-S curve can get the single pile vertical ultimate bearing capacity. Regression analyse the relationship of single pile vertical ultimate bearing capacity and end pressure by mathematical statistics method can build the area experience formulas about the relationship of fiction-type and end bearing static pressing pipe pile＇ s end pressure and single pile vertical ultimate bearing capacity when clay and sandy is the supporting course. These formulas provide reference to de- sign and construction of similar projects. It has very important impellent effects on static pressing pipe pile＇ s generaliza- tion and application to Xi＇an city.
