【摘要】：针对博贺中心渔港透空式防波堤地基岩面非常浅,桩基透空堤不适用的问题,对典型的重力式防波堤进行创新设计,利用箱涵的透流特性和削角直立堤的防浪特性,将两者进行组合,提出箱涵式削角直立堤的新型透空堤结构方案。通过理论分析和物模论证,认为该结构安全可靠,达到防浪、透流、减少回淤等功能要求。通过初步经济效益分析,认为该结构有助于港内水体交换,可作为环境保护措施;降低年淤积强度,减少疏浚维护费用。
[Abstract]:In view of the very shallow rock surface of the porous breakwater in Bohe central fishing port and the inapplicability of the pile foundation impervious breakwater, the typical gravity breakwater is innovatively designed, and the characteristics of the box culvert and the bevel vertical breakwater are used to prevent the wave. A new type of perforated embankment structure with box culvert angle cutting vertical embankment is put forward. Through theoretical analysis and demonstration of physical model, it is considered that the structure is safe and reliable, which can prevent wave and permeate current. Based on the preliminary economic analysis, it is considered that the structure is helpful to the exchange of water in the harbor and can be used as an environmental protection measure, and the annual siltation intensity is reduced, and the maintenance cost of dredging is reduced.
