Abstract: | According to the geological conditions of JinBin Expressway soft ground and construction characteristics,composite foundation such as replacement method, mixing pile and PTC pile was cho- sen in accordance with settlement standards. After nearly two years, settlement observation data anal- ysis show that the measured settlement fully meet the specification requirements and the driving is also comfortable. |
