现状我国近几年来,建造高层建筑逐渐增多,如何处理好地基基础是很重要的问题。目前,高层建筑的基础主要有三种形式:1.结合地下室埋深要求,用箱形基础天然地基。2.当填土层、持力层较深,超过地下室埋深时,一部分工程采用预制钢筋混凝土桩基。3.当遇土质软、填土层厚,持力层特别深地区,较多推广使用大直径钻孔灌注桩基础。最近又试行了扩大箱形基础、补偿式基础、短桩加箱基和地下
The status quo In recent years, the construction of high-rise buildings in China has gradually increased. How to deal with the foundation of the foundation is an important issue. At present, there are three main forms of high-rise building foundations: 1. Combine the requirements of the depth of the basement and use the natural foundation of the box foundation. 2. When the filling layer and bearing layer are deep and exceed the depth of the basement, some of the projects use prefabricated reinforced concrete piles. 3. When the soil is soft and the filling layer is thick and the bearing layer is in a particularly deep area, the use of large-diameter cast-in-place bored pile foundations is promoted. Recently piloted the expansion of box foundations, compensation foundations, short piles plus tanks and underground
