挤实砂桩法是1956年日本开发的一种快速加固软基的方法,它利用冲击或振动在软基中形成密实的砂桩,用于加固松砂、软粘土、吹填土、冲积平原、沼泽地、山谷和海底等软土地基。该方法目前已广泛应用于工业民用建筑、油罐、高速公路和铁路路基、机场跑道、堤防和闸坝、防波堤和岸壁、堆场、护岸和河川等构筑物的地基加固,总施工进尺已达6,000万米以上,在设计理论方面也比较完整,成为一种成熟的软土地基加
Squeezed sand pile method is developed in Japan in 1956, a rapid reinforcement of soft base method, which uses the impact or vibration in the soft base to form dense sand piles, for strengthening loose sand, soft clay, dredging fill, alluvial plain , Soft soil foundations such as marshes, valleys and seabed. The method has been widely applied to the foundation reinforcement of industrial civil buildings, oil tanks, expressways and railway subgrade, airport runways, embankments and sluices, breakwaters and quayside, yard, revetments and rivers, and the total construction footage has reached 6,000 More than a million meters, in the design theory is relatively complete, to become a mature soft ground
