摘要
为了研究长短桩复合地基在高速公路软土地基处理中的应用,通过设计现场试验,对地质条件相似路段分别采用塑料排水板、浆喷桩、长短桩进行地基处理,对3种地基处理方法的表层沉降、分层沉降及水平位移进行监测对比,发现长短桩复合地基优于塑料排水板及浆喷桩,最后对3种地基处理方法进行技术经济比较,得出长短桩复合地基处理方法具有较高的经济性。
In order to study the use of long-short pile composite foundation in the soft foundation of highway, the field tests were designed. Plastic drainage board, Gunite pile and long-short pile were used separately in the treatment of the sections with similar geological conditions.The surface settlement ,layered settlement ,and horizontal displacement of the three treatments mentioned befor were monitored and compared,we found that the treatment effect of long-short pile composite foundation is better than the others. Finally, combining with the economic comparison of the three kinds of foundation treatment methods ,obtained that the long-short pile composite foundation has high economical efficiency.
