低应变动测桩中波的传播规律研究

Study on the Transmit Rules of Stress Wave for Low Strain Test Pile

低应变动测桩中波的传播过程较为复杂,对低应变动测桩,桩侧土阻力波和桩身上、下行波的传播规律进行了理论研究,阐述了桩侧土、桩底土对桩身上、下行波传播过程中的不同影响,得到了桩中波传播过程的空间网线图以及桩身不同截面处的各参数的传播规律图,直观地反映了桩中波的传播过程.

The transmit course of stress wave for low strain test pile is a complicated problem.The transmit rules of resistance wave of soil around pile and upward traveling wave and downward traveling wave of pile for low strain test pile are studied,Theoretically with the calculation program programmed according to the theory stated in literatures,and the impaction of different soil around and below the pile for transmit process of upward and downward traveling wave in pile are stated.The mesh of traveling wave and...
