据日本《建筑技术》报道,日本大林组公司利用水平振动(扭转振动)以及水平和垂直合成的复合振动砂桩法对地基进行加固,并在多项工程中取得较好效果。该法有如下特点:1.使地基均质化采用研制的特种起振机(复合振动桩锤),可使垂直振动和与此同时沿环向产生水平扭转振动,以及这两种振动合成的复合振动任意转换起振,而通过装在套管顶端的翼板,又 According to Japan’s “Architecture Technology” report, Japan’s Dalin Group Corporation uses horizontal vibration (torsional vibration) and horizontal and vertical composite vibration sand pile method to reinforce the foundation, and achieved good results in many projects. This method has the following characteristics: 1. The use of a special type of vibrating machine (composite vibratory pile hammer) for the homogenization of the foundation allows vertical vibration and horizontal torsional vibration in the circumferential direction, as well as the combination of these two vibrations. The composite vibration oscillates arbitrarily and passes through the wing plate mounted on the top of the casing.
