The author excogitated a kind of appropriative mud jacking material which is made up of cement, sand, fly ash, admixture and water. this material which was developed on the basis of large amount of tests has the proprieties of good self - flowing density, high earlier strength, non - segregation, non - weepage and non - contractility. especially, the author aim at dealing with pumping mud and earlier maintained developed a kind of high flow grade material which can meet the requirement of mud jacking
本文研製了專用壓漿材料，採用水泥、砂、粉煤灰、外加劑和水混拌而成，通過大量實驗配製出的漿液具有自流淌密實性好、早期強度高、無離析、無泌水、無收縮的性能，特別是針對路面唧泥處理或預防性養護，板底脫空量較小，研製出高流動度材料，能滿足壓漿施工的需要。 -
In this paper, the best reinforcement scheme, which was found by nerve network and genetic algorithm from serval reinforcement schemes, was applied to strengthen a prestressed concrete continuous rigid fame bridge with many quanlity faults, such as excess fall deflection of the main span deck > serious web slop crack existing between main pier abutment and one fourth span, and very poor mud jacking quanlity in the prestressing tendon tubs
本文針對某預應力混凝土連續剛構橋所存在的實際問題：如主橋橋面下撓度過大；主墩和四分之一跨徑處均存在較嚴重的腹板斜裂縫；預應力管道壓漿質量較差等。提出了幾種加固方案，並用神經網路和遺傳演算法進一步優化出了較佳的加固方案，進行了加固前後效果對比分析。 -
