桥梁桩基桩身荷载量测与应力波法测试中的参数

通过某高速公路桥梁桩基试桩测试,分析了静载荷试验中的桩身内力、荷载传递规律、土阻力的发挥等,与应力波法高应变测试结果进行对比分析,进一步说明动力测试中各种参数只有通过静载荷试验检验后,才能应用于工程的大规模检测。

Static Load Test on Pile of Bridge and Interrelated Parameters in Stress Wave Test

In recent twenty years, dynamic load tests using stress-wave theory have been used rapidly in pile foundation. Based on the static load test on the foundation of bridge in one highway, the load along pile, the load transfer law and the side friction resistance of some piles in two typical locations is discussed in this paper. The results show that the parameters in high strain test must be detected by static load test before the application in the highway.
