本文针对某预应力混凝土连续刚构桥所存在的实际问题：如主桥桥面下挠度过大；主墩和四分之一跨径处均存在较严重的腹板斜裂缝；预应力管道压浆质量较差等。提出了几种加固方案，并用神经网络和遗传算法进一步优化出了较佳的加固方案，进行了加固前后效果对比分析。 - 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
本文研制了专用压浆材料，采用水泥、砂、粉煤灰、外加剂和水混拌而成，通过大量实验配制出的浆液具有自流淌密实性好、早期强度高、无离析、无泌水、无收缩的性能，特别是针对路面唧泥处理或预防性养护，板底脱空量较小，研制出高流动度材料，能满足压浆施工的需要。
