| 摘 要： | 当前加层房屋日益增多,其地基加固处理的方法很多。在确定加固方法之前,需对旧楼地基基础及结构进行验算,包括桩端持力层的强度,桩的容许承载力,桩基础沉降等。水泥-水玻璃双液化学灌浆法首次用于房屋增层地基加固,该方法具有可灌性高(K=10-6cm/s)、凝胶时间快(15~120 s)、强度较高(5~20 MPa)等诸多材料特性,可满足新增的上部结构荷载对地基的新要求。文章还介绍了一个工程实例

| Abstract: | At present the situation of adding stores on old buildings is increasing day by day.There are many methods of ground consolidation.Before consolidation method is determined,the foundation and structure of old buildings need checking,such as strength of supporting layer where the pile end is,allowable bearing capacity of the pile,subsidence of pile foundation and so on.Cement water glass grouting method is used to ground consolidation of adding stores buildings,this method has a lot of specific material properties,such as,grouting property is high(K=10-6 cm/sec),coagulate time is quick (15~20 sec),strength is higher (5~20 MPa),and it can satisfy the new requirements of the ground for adding upper structure load.This paper also introduces an engineering example. |
