摘要
以固镇船闸的施工实例 ,介绍了在不排水抗剪强度cu 值小于 2 0kPa的软弱淤泥地基中 ,采用振冲碎石桩加固的施工方法和控制措施 ,并通过载荷试验得出加固后的承载力数值 。
Taking the construction of Guzhen Shiplock as example, the construction method and control measures for adopting vibro impact broken stone piles to strengthen soft weak foundation of which the shear strength C\-u is lower than 20 kPa under condition of without drainage, are described. And through the loading test, the upgraded bearing capacity of the foundation after its strengthening has been obtained. On these grounds, an economic design scheme is adopted. [
