摘要
针对我国高速公路涵洞及桥台位置回填土压实度难以控制,易产生不均匀沉降从而导致桥头跳车普遍的现象,从回填材料、分层厚度、密实度、回填深度四个方面简要探析台涵背回填土质量的检测方法,通过对台涵背回填土抽芯法检测的研究分析,为台涵背回填土的检测提供一种有效便捷的检测方法,从而为其施工及管养提供依据。
In view of the fact that the compactness of backfill soil in culvert and abutment position of expressway in our country is difficult to control,and it is easy to produce uneven settlement,which leads to the common phenomenon of vehicle jumping at bridgehead,this paper briefly analyzes the detection method of backfill quality of culvert back from four aspects:backfill material,layering thickness,compactness and backfill depth,and through the research and analysis of the detection given by backfill core drilling method,it provides an effective and convenient method to detect the backfill of culvert,and furthermore,a basis for construction and management.
