| 摘 要： | 利用灌注桩应力测试结果,对桩底沉渣对桩的荷载传递影响进行分析。试验结果表明,桩底沉渣不仅影响桩端阻力发挥,而且也影响桩侧阻力发挥,桩底沉渣越厚,桩侧阻力发挥值越小。同时根据桩的荷载传递特征,提出桩的承载力估算方法。

| Abstract: | According to cast-in-situ pile stress test results,it is analyzed the influence of pile bottom slime on the pile load transfer.Test results indicate that pile bottom slime has influence upon not only tip of pile resistance,but the skin friction.The pile bottom slime is thicker,the skin friction is smaller.Simultaneously according to the characteristics of load transfer of piles,the estimation method is proposed about the bearing capacity of pile. |

| Keywords: | pile bottom slime construction technology skin friction load transfer bearing capacity |
