摘　　要：根据宝钢马迹山港卸船码头岩基段的地质特点,桩基础设计采用全直桩嵌岩方案.为保证施工期钢套管的稳定,用抛填碎石层形成人工基床.为了验证该施工方案的可行性,进行了波浪和水流共同作用下,嵌岩桩施工期钢套管的稳定性试验,并对试验与理论计算结果进行了对比分析.结果表明,8.0 m基床厚度可以保证钢套管的稳定.According to the geological characteristics of the rock foundation of the Majishan ship unloading terminal at the Baoshan Steel works, rock-socketed straight piles were adopted for pile foundation. A manual foundation bed formed by filled ballast was employed to ensure the stability of the steel casing pipe during the construction period. Under the combined actions of waves and currents, the stability of the rock-socketed pile during the construction period was studied, and a comparison of experimental and theoretical results was made. The results show that the proper depth of the foundation bed is 8 m.
