针对某高速公路拓宽改建中出现的路基开裂及地基中存在泥炭土层问题,研究提出了采用挤密混凝土桩进行处理的新方法,从而达到对既有道路影响小,同时桩体强度不受泥炭土层影响的目的。其成果可供类似工程问题处理予以借鉴。
Aimed at the cracking of roadbed and the existence of peat soil layer in a widening and rebuilding of a highway, a new method of dealing with crowded concrete piles was put forward to achieve the effect of small impact on the existing roads and the strength of the pile body from peat The purpose of soil effects. The results can be used for reference to similar engineering problems.
