摘　　要：斜柱挖孔桩基础在国外线路工程中已有应用,在国内仍是一种新的基础结构型式。通过对斜柱挖孔桩基础进行真型试验,采用模拟送电线路直线塔受压时实际工作条件的试验方法,验证了桩基础竖向抗压及水平承载力的设计理论、方法以及设计参数取值的合理性、可靠性。试验结果表明:该基础型式在设计荷载范围内,结构是稳定、安全的。Obliquely inserted excavation pile base has been employed in overseas line engineering while it remains fresh in China. By full-scale test on obliquely inserted excavation pile base and test method in operating condition of straight-line tower pressure of simulated transmission line, reasonableness and reliability of design concept, methodologies and design pa- rameter values for vertical pressure resistance and horizontal bearing capacity of obliquely inserted excavation pile base are verified. The test result indicates that the base type is structurally stable and safe in the range of designed load.
