长短桩复合地基在高速公路软基处理中的应用
The application of long-short piles composite foundation in highway soft foundation treatment
摘要
Abstract
In order to study the application of long-short piles composite foundation in lakes soft ground treatment, highway soft foundation treatment in lake areas is tested by long-short-pile composite foundation. A series of static loading tests of long-shortpile composite foundation on single pile have done, and the monitoring results of subgrade settlement were analyzed. The results show that ultimate bearing capacity of a pile composite foundation is about 240kPa, which is bigger than design value 127kPa. The settlement after construction is only 1.3ltm, so the long-short pile treatment technical for lake soft ground is reasonable and reliable.关键词
