在目前码头结构型式的基础上提出了利用土工织物散体桩进行深厚软基处理的技术,扩大了重力式码头的应用范围,使其能在深层软土地基中得以使用,在满足地基承载力及稳定性的前提下达到经济、环保、高效的目的。深厚软土之上的土工织物散体桩与浅层软土构成的复合地基类似于"硬壳层"地基的工程特性,形成较大的地基承载力。对土工织物散体桩处理的码头软基破坏机理进行了较为系统的分析,并通过与刚性桩的对比分析了优缺点。 相似文献

地基稳定验算是保证高桩码头接岸结构安全的重要步骤,而选用什么样的地基稳定验算方法至关重要。针对这个问题,结合工程案例,选用简单条分法和复合滑动面法进行抗力分项系数计算比较,并提出了软弱夹层处理方案。同时在原设计方案基础上,结合两种方法对软弱夹层关键参数黏聚力、内摩擦角和厚度进行敏感性分析,并对抗力分项系数进行了相关性分析。结果表明:存在软弱夹层的高桩码头接岸结构应同时采用简单条分法和复合滑动面法进行地基稳定验算;在同样变化率下,内摩擦角对抗力分项系数的影响明显高于黏聚力的影响;两种方法计算的抗力分项系数最小值在一定条件下具有高度相关性。结论可为类似条件下高桩码头接岸结构地基稳定验算提供一定的参考。 相似文献
