湿陷性黄土地区钻孔桩承载力试验研究

通过对豫西湿陷性黄土地区郑西客运专线9座桥梁钻孔桩承载力试验研究,并以枣香河特大桥试桩的单桩竖向极限承载力、水平单桩水平静载试验和摩阻力试验为例,从试验方法、数据分析等方面进行了阐述,通过试验研究结果对钻孔桩设计参数进行了优化,既方便了施工,又创造了效益。

Experimental research on bored pile bearing capacity of wet collapsible loess areas

Through the experimental research on bored pile bearing capacity of Zhengzhou-Xi＇an passenger dedicated line nine bridges wet collapsible loess areas,and taking single pile vertical ultimate bearing capacity of Zaoxianghe large bridge test pile,single pile horizontal static load test and frictional resistance test for example,elaborated from test method,data analysis and other aspects,through the experimental research results optimized the design parameters of bored pile,which was convenient for construction,and created efficiency.
