ABSTRACT: Located in the southwest of Guangdong Pearl River mouth, Zhuhai city is the core city along the west bank of Pearl River mouth with marine depositional plain as the major geomorphic unit and soft soil in large distribution. Due to particularity of geographical formation mechanism, the soft soil here is of high moisture capacity, high compressibility, lower bearing capacity. Zhuhai golden harp in the north of highway Starting from Golden Harp in the north of Zhuhai city and ending at Hengqin Port, the engineering project of Jinqin highway goes through various water channels and seaboards with very complex geological conditions. Through understanding the harms caused by soft foundation in highway construction as well as related treatment measures, we put forward reasonable treatment measures for the problems caused by soft soil foundation, especially the application of cement mixing pile in soft foundation treatment problems so as to achieve the higher smoothness, safety and durability in construction of highway.
