| 摘 要： | 通过高应变动测试验和静载荷试验,对深厚软土地基中PHC管桩的受力特性进行了研究,探讨了深厚软土地基中超长PHC管桩的竖向承载特性和荷载传递机理.结果表明,高应变动测试验和静载荷试验得出的极限承载力结果很接近.在深度小于30 m时,动静试验所得的侧摩阻力比较接近,但是随着深度的加深,动测试验所得的侧摩阻力比静载试验要大.

| Abstract: | The bearing capacity behavior and load transfer mechanism are discussed through static and high strain dynamic pile load testing. Results show that the total bearing capacity of test piles by high strain dynamic testing is approximately equal to that by static testing. The lateral friction resistance by dynamic testing is consistent with that by static testing at the depth of 0-30m,but is much larger than that by static testing when the length of the pile exceeds 30 m. |
