摘要
大型中转港码头均拟建在近海的深水区,码头傍依的海岛基岩起伏大,桩基工程地质条件复杂。通过宝钢马迹山港卸船泊位软基区打入桩试桩和基岩区嵌岩桩水平荷载试验,结合地层发育情况,对坡洪积、残积土层的沉桩特征及受水平荷载嵌岩桩的桩顶水平位移、弯矩特点进行了分析。提出了在此类桩基工程地质勘察中进行全曲线重型动力触探试验的必要性。
All wharfs of Large-sized transshipment ports are built in offshore deepwater zone with rising and falling bedrock and complex geological conditions for construction of pile base. Based on horizontal loading tests for testing driven piles in soft ground area and rock-imbedded piles in bedrock area in Majishan port ship unload berth of Baoshan Steel Works, analysis is made on pile sinking characteristics of slope diluvium and eluvium, horizontal displacement of pile top and bending moment of rock-embedded piles under horizontal load, in view of ground development conditions. The necessity to carry out full curved heavy dynamic sounding test in geological survey of such pile footing construction is proposed also.
