重力式结构是码头和防波堤建筑物中一种主要的结构型式。重力式结构的基本特点是依靠自身重量来保障建筑物的抗滑和抗倾稳定性。在核算重力式建筑物沿基床面的抗滑稳定性时,抛石基床面与预制混凝土块体之间摩擦系数的取值是一个关键问题——取值偏大,结构抗滑稳定性不足;取值偏小,结构断面无谓的加大,造成浪费。所以,对抛石基床面与预制混凝土块体之间的摩擦系数的取值问题有必要进行深入地研究、探讨。
Gravity structures are one of the major structural types in piers and breakwater structures. The basic feature of the gravity structure is to rely on its own weight to protect the building’s anti-slip and anti-dumping stability. The value of the friction coefficient between the riprap-based bed and the precast concrete block is a key issue in the calculation of the anti-sliding stability of the gravity-type building along the bed. Insufficient; the value is too small, the structure of the section unnecessary increase, resulting in waste. Therefore, it is necessary to conduct in-depth research and discussion on the value of the friction coefficient between the riprap-based bed and the precast concrete block.
