In this paper , research on predicting service life of reinforced concrete component exposed to chloride environment was made : firstly , a finite difference model is developed for predicting the process of chloride penetrating into concrete 本文對氯離子侵蝕環(huán)境下鋼筋混凝土結(jié)構(gòu)耐久壽命預(yù)測進(jìn)行研究,完成以下一些工作:首先,綜合考慮多種因素影響,建立有限差分計算模型。
1 . on the bases of some basic suppositions , terzaghi ' s one dimensional consolidation and principles of layered summation method , the paper draw the formula which can calculate the embankment of layered filling and take the formula into programme ; 2 . building the finite difference model of layered high - stack soil , carrying out numerical simulation of construction sequence , construction velocity , interface element of layer - stacked , the author get the numerical solution 1利用一些基本假定,根據(jù)太沙基一維固結(jié)理論和分層總和法的基本原理,推導(dǎo)出來計算分層填筑體自身沉降的公式,并編制了程序; 2建立了分層填筑高填方路堤問題的有限差分模型,并對分層填筑的施工順序、施工速度,界面單元進(jìn)行了數(shù)值模擬,獲得了位移場和應(yīng)力場的數(shù)值解。
