国内现有的地基加固技术对于深厚的软粘土层各有其不适应性,因此大力发展新的加固技术越来越受到人们的重视。冶金部建筑研究总院同交通部水运规划设计院协作,从1977年10月开始进行了深层搅拌机械研制和室内外试验。1980年上海宝钢五冶参加
The existing ground reinforcement technology in China is not adaptable to the deep soft clay layers. Therefore, the development of new reinforcement technologies has received increasing attention. The Ministry of Metallurgical Construction Research Institute collaborated with the Ministry of Transport’s Water Transport Planning and Design Institute. From October 1977, deep mixing machinery development and indoor and outdoor tests were carried out. In 1980, Shanghai Baosteel participated in Wuye
