钙质砂地基桩侧摩阻力影响因素分析

Analysis on the Influencing Factors of the Pile Shaft Resistance in Calcareous Sand Foundation

钙质砂是一种海洋生物成因的特殊岩土介质,在钙质砂地基中的桩基工程又很常见。桩侧阻力的研究是桩基承载力性状研究中的一个重点,由于受到诸多因素的影响,桩侧阻力的计算变得十分复杂,本文通过对桩长、桩径、桩周土性质、桩端土强度、时间长短等诸多影响因素的讨论,发现不同条件下桩侧阻力的变化具有一定的规律性,且这些因素有着相互的联系,并提出今后重点研究方向。

Calcareous sand is a cause of special marine geotechnical medium,pile foundation works are not uncommon in the calcareous sand.Study of pile shaft resistance is a key point of the research on the pile bearing performance.Because of being influenced by many factors,the calculation of the shaft resistance become a very difficult problem.According to the discussion of the influencing factors,such as the length of the pile,the radius of the pile,the feature of the soil layer,the strength of the pile end,the influence of time etc,they contact with each other.Some important study tendencies in the future are proposed.
