钻孔灌注桩施工过程问题研究

钻孔灌注桩以其承载力大、造价低等特点，越来越广泛地运用于桥梁和高层建筑的基础。在施工过程中，任何一个环节出现问题，都将直接影响到整个工程的质量和进度，而采用优质泥浆降低失水量等有效方法进行施工，效果显著，值得推广。

Problems in Bored Pile Construction Process

Because of great bearing capacity, low cost and other characteristics, bored piles are used in the foundation of bridges and high-rise building more and more widely. In construction process, whichever step presenting itself problems will affect the quality and progress of engineering directly. Using high grade slurry to debase water loss and other effective methods are of marked effect in construction, so they are worthy of wide popularization.
