对65根嵌岩桩轴向静载荷试验结果进行了对比分析,将嵌岩桩的试验结果以及收集到的文献试验数据形成实测数据库,与经验方法预测结果进行了比较。提出了嵌岩桩单位极限侧阻力的分段线性函数预测方法和平方根预测方法,线性分段函数预测方法取决于岩石类型和岩石无侧限抗压强度。
The axial static load test results of 65 rock-socketed piles were compared and analyzed. The test results of rock-socketed pile and the collected experimental data were formed into the measured data base and compared with the predicted results of the empirical method. The piecewise linear function prediction method and the square root prediction method for the unit lateral resistance of rock-socketed pile are proposed. The prediction method of linear piecewise function depends on the type of rock and the unconfined compressive strength of rock.
