| Summary: | Marine structures are defined as a human made structures which are constructed for the purpose of port facilitiesand/or protecting the coastline, This research focus on studying and analyzing the stability of an important type ofmarine structure which is: concrete block quay wall, optimum design and stability of pre-cast concrete blocks quaywalls consists of 15 row of blocks numbered respectively from bottom to top using the hollow blocks instead ofsolid ones by obtaining the resulting benefits of this replacement is investigated. Therefore, four stages ofoptimization under stability considerations have been adequated as. GEO5 software had been used for the purposeof determining the factors of safety against overturning and sliding for all structure and at each block interface andalso determining the bearing pressures exerted by the quay wall to the existing ground for structural elements underall load combinations for all stages of optimization and using these pressures in hansen's equations for studying thestability of the block quay wall against (bearing capacity). SLOPE/W software had been used also for studying thestability of block quay walls against slip failure. The results show that the critical stage of optimizations is opt.(2),reducing the backfill internal angle of friction (φ) from 40˚ to 30˚, reduces the factors of safety against Bearingcapacity and slip failure and Increasing the subsoil cohesion parameter (c), improves the bearing capacity factor ofsafety. |
