引言随着社会经济发展的迅速发展,高层建筑越来越成为城市里的一道亮丽风景线。冲孔混凝土灌注桩作为高层建筑地基处理最常见的方法之一。它具有承载力大,沉降量小,地质适用范围广等优点。而桩底注浆技术是近年来常用的配合冲(钻)孔灌注桩一种地基处理技术,它能最大限度的发挥冲(钻)孔灌注桩的优点,克服冲(钻)孔灌注桩的一些劣势和不足,满足高层建
Introduction With the rapid development of social and economic development, high-rise buildings are increasingly becoming a beautiful landscape in the city. Perforated concrete bored piles are one of the most common methods for foundation treatment of high-rise buildings. It has a large carrying capacity, small settlement, a wide range of geological applications. The bottom grouting technology is a kind of foundation treatment technology commonly used in recent years to cooperate with punching (drilling) bored piles. It can maximize the advantages of punched bored piles and overcome the problems of punched (drilled) bored piles Some disadvantages and deficiencies, to meet the high-rise building
