湿陷性黄土地区水泥生产线地基处理方法的选择

Option for foundation treatment methods of cement production line in collapse loess area

我国湿陷性黄土共分为七个分区,总面积达60多万km2。对湿陷性黄土区的建筑物,其设计措施通常可采取:地基处理措施、防水措施和结构措施三种。对位于湿陷性黄土地区的水泥工厂,由于其建(构)筑物的特点,必须采用以地基处理措施为主,防水措施和结构措施为辅的设计原则。在详细介绍常用地基处理方法的技术特点和适用条件的基础上,重点介绍了处于湿陷性黄土区的大通河水泥有限公司1000t/d技改工程和冀东水泥扶风有限责任公司4000t/d生产线中相关建(构)筑物采取的桩基工程的设计方案,及其实施措施及效果。

Collapse loess area in China covers an area of more than 600,000 km^2 in seven subareas. Common used measures in design of buildings in collapse loess area are mainly focused in three aspects： foundation treatment, waterproofing, and structure. Due to the unique architectural and structural characteristic, the design principle of cement plant built in collapse loess area should be： taking the foundation treatment as main measure, the waterproofing and structural methods as auxiliary measures. Based on introducing the popular used foundation treatment technology and respective conditions, this paper presents foundation design of relative buildings and structures in 1000t/d line of Honghe Cement Co., Ltd and 4000t/d line of Jidong （Fufeng） Cement Co., Ltd, as well as the practical experience and consequent effects.
