The main contents are as follows. ( 1 ) filter cloth and the surrounding soil mass are taken as an approximate isotropy in horizontal section, the relationship of stress and strain is studied, the anisotropy is fully considered, the constitutive model of filter cloth reinforcement fly - ash compound is obtained, it is tested with numerous indoor experiments. ( 2 ) the permeable coefficient is introduced into the constitutive relationship of soil mass with relevant seepage theory ( kozeny - carman experience formula ). the test of filter cloth depositing hi the condition of long term seepage flow is done hi the dissertation, the varying regular of permeable coefficient without pressure is presented
本文首先對國內外的研究現狀作了回顧和總結,然後主要針對土工織物加
筋粉煤灰復合體的本構關系和計算理論進行研究,主要內容有: ( 1 )將土工織物和周圍土體視為
一種近似的彈性非線性橫觀各向同性體,研究它的應力應變關系,充分考慮它的各向異性,得到土工織物加
筋粉煤灰復合體的本構模型,然後通過大量室內試驗進行分析驗證; ( 2 )引入有關滲流理論,即柯茲尼-卡爾曼( kozeny - carman )經驗公式,將滲透系數引進到土體本構關系中。

Simultaneously, combine with his own work experience, the author gets an advanced detail and general design steps. and then illustrates an actual engineering which is designed with the article ’ s recommendatory method and steps. by combining with the test results, it is proved that the ground treatment result obtains the design requirement and the commendatory method is right, which is able to provide reference value to the engineering
本文首先對加
筋土的研究現狀做了詳細的介紹和分析,在此基礎之上,對加
筋土地基設計方法做了
一定的研究,對地基承載力力設計方法做了對比分析,選擇極限分析法作為本文的推薦方法,並結合作者自身的工作經驗,提出了加
筋土地基詳細和全面的設計步驟,然後用
一個加
筋土地基實際工程為例,採用本文推薦的設計方法和步驟進行設計,並通過現場試驗結果,證明該地基處理達到設計要求,也證明了推薦方法計算的準確性,這對廣大工程師在實際工程操作中有較高的參考價值。
The research is that : after the same cyclic number of loading times, the steel stress of reinforced beams was much smaller than that of common beam ; the deflection of reinforced beams was decreased by 40 % - 50 %, therefore, the anti - transformation of the reinforced beams is enhanced greatly

The deflection formula both used in classic rc theory and in rc code is correspond to service state. however after rc members strengthened with frp, the main rebar is under the post - yielding stage. therefore the normal deflection formula is not suitable for calculating the deflection of rc members strengthened with frp
但由於鋼筋混凝土構件加固后,受拉主筋一般都進入屈服階段,否則達不到加固效果;而經典鋼筋混凝土理論和我國規范中的計算公式都是針對構件處于正常使用狀態下的變形計算。
