Thrusted-expanded lime-soil compaction pile method thrusted-expanded a hammer and lime-soil compaction fill the integration of soil to achieve the purpose of the rule territories through the pile of soil compaction of the salt and lime-soil filling replacement, cementing sclerosis Such as the role of soil has been effective reinforcement.

柱锤冲扩灰土挤密桩法将柱锤冲扩成孔与灰土填料挤密相结合，实现了以土治土的目的，通过对桩周土体的挤密和灰土的冲填置换、胶凝硬化等作用使地基土体得到了有效的加固。

3D effect is analyzed and the average velocity of wave propagating in the pile, which mainly influences inverse interpretation, is discussed. Finally, the theory results are verified by model experiment. It is shown that 3D results have the same phase with ID results. The pile radius, the duration of impulse, the ratio of hammer radius to pile radius and shear velocity of the soil around the pile have influences on 3D effect. The best position of receiver is 0.55R from the pile center. The average velocity of wave propagating in the pile reduces due to transversal inertia effect and 3D effect.

结果表明：三维曲线与一维结果在相位特征上一致；波场图直观地反映了波在桩中的传播规律；三维效应与桩径、激振脉冲宽度、相对激振半径及桩周土剪切波速有关；传感器放在0.55R处可以得到干扰较小的信号；三维效应和横向惯性效应的存在会使桩中的波速减小，土的性质对波速影响不大；反演精度与缺陷的性质、激振条件有关。

The northern sea wall in Gudong Oilfield at Yellow River Delta needed reinforcing so that the feasibility of three kinds of offshore driving pile construction methods was analyzed in consideration of the sea conditions of weather, hydrology and geology in Yellow River Delta area. Finally the driving pile construction scheme using vibrating hammer and piling catamaran was chosen.

黄河三角洲胜利孤东油田北海堤需要加固维修，针对黄河三角洲海域的气象、水文、地质条件，分析了3种海上沉桩施工方案的可行性，最终选择了振动锤双体打桩船沉桩方案。

Testing results of piles under low strain integrity are normally interpreted using one-dimensional stress wave theory. While one-dimensional stress wave theory is acceptable for pile-driving analysis the responses of piles integrity tests can not be adequately simulated when the hammer and the incident wave length are small in relation to the diameter of the pile.

基桩动测问题的理论基础一维应力波理论只有在锤径桩径比、波长桩径比、桩长桩径比足够大时才能近似成立，否则该问题实际上为应力波在柱体中传播的三维问题。
