赤湾港10万吨级深水泊位配套的面粉厂,位于填土厚度20余m的高填土区,新填土较松软,且含大量块石,填土之下又有10余m厚的软弱土层和10m左右风化残积层。在这样复杂的地质条件下,用两种冲孔桩基础,解决了含大块石的高填土区桩基负摩擦和承载力问题。文中还介绍了一种新型的冲孔灌注桩——建新桩在赤湾港的应用情况。
Chifeng Port 100,000-ton deepwater berth supporting flour mill, located in the fill area of 20 m high filling area, the new fill is more soft, and contains a lot of rock, under the fill there are more than 10 m thick Weak soil and about 10m weathered residual layer. Under these complicated geological conditions, two kinds of punched pile foundations are used to solve the problem of negative friction and bearing capacity of pile foundation in high filling area containing large stones. The paper also introduced a new type of perforated piles - the application of new piles in the port of Chiwan.
