摘要
20世纪 70年代以来 ,强夯法加固填土地基技术得到了广泛的应用 .论述了强夯法加固地基的基本原理 ,并运用该原理提出了用强夯与置换相结合的地基处理方法对饱和软土地基进行加固 ,形成理想的复合地基 ,达到加固地基并提高承载力的目的 .结合秦皇岛港戊己码头己堆场工程地基加固的工程实例 ,讲述了强夯置换的施工技术要求、施工工艺与参数以及处理后经过检测所取得的良好效果 ,最后又说明了该方法的优点及应用前景 .本工程是理论与实践的成功结合 ,进一步拓宽了强夯法的应用范围 .
Foundation consolidated by dynamic rammer has been applied widely since 1970's.The paper discusses the principle of heavily ramming and a method through combining it with replacement is provided for saturated and soft soil ,by which an ideal compound ground is shaped and we can also consolidate the ground and improve the weight bearing of the ground .In addation ,according to the example of the project of Qinhuangdao,the article introduces the standard of construction technique,construction craftwork,parameters and the good effect after treatment ,at last, the advantage and application area of the technique is stated. The project is a successful combination of theory and practice,and widen the application range of heavily ramming.
