直立式防波堤抛石基床与混凝土沉箱底画间摩擦系数(f)是正确预估防波堤沿基床面抗滑稳定性的重要参数,它直接影响整个工程的造价。马耳他马尔萨什洛克港直立式沉箱防波堤工程利用当地低强度珊瑚石灰岩(抗压强度300～500公斤/厘米~2)作为基床抛石料。为了确定基床摩擦系数,进行了大比尺模拟试验。本文阐述该试验所得结果。
The coefficient of friction (f) between the upright breakwater bank and the bottom of the concrete caisson floor is an important parameter for correctly predicting the anti-skid stability of the breakwater along the bed. It directly affects the cost of the whole project. Malta Marsaxlokk Harbor upright caissan breakwater project using the local low-intensity coral limestone (compressive strength of 300 to 500 kg / cm ~ 2) as a bedrock. In order to determine the bed friction coefficient, a large scale simulation test was carried out. This article describes the results of this experiment.
