直立钢管桩防波堤是一种新型防波堤,它的特点是:(1)结构简单,重量轻;(2)钢管桩可穿过软弱土层,支持在土质较好的土层上,使得防波堤沉降小;(3)海水对钢管桩的腐蚀,波浪飞溅区最严重,海底附近较轻;而直钢管桩的弯矩,波浪飞溅区较小,海底附近较大。所以结构较为合理;(4)海上作业少,施工快。正是基于上述特点,这种类型防波堤在日本和我国援外工程中,相继被采用。
Vertical steel pipe pile breakwater is a new type of breakwater, which is characterized by: (1) simple structure, light weight; (2) steel pipe pile can penetrate the weak soil layer, support in the soil of better soil, making the breakwater (3) Corrosion of seawater on steel pipe piles has the most serious wave spatter area and lighter near seafloor. However, the bending moment and wave splash area of straight steel pipe piles are smaller and larger near the sea floor. So the structure is more reasonable; (4) less offshore operations, construction faster. It is based on the above characteristics that this type of breakwater has been adopted in Japan and China’s foreign aid projects.
