To meet the need of settlement calculation with fem when absence of laboratory triaxial test data in common road engineering, methods of determining the five parameters included in tangential elastic module through soil routine tests and the related emendation coefficient are given. at the same time, one approximately substituted formula for tangential poisson ratio is also developed, which is suitable for both sandy soil and cohesive soil. ( 3 ) research on main parameters modification of duncan - chang model based on the improved bp network
對於一般道路工程中不做三軸試驗但須進行沉降有限元計算的情況，給出了依據土體常規試驗的切線彈性模量確定方法和相關修正系數，同時也提出了對砂性土和粘性土均適用的切線泊松比的近似替代式子； （ 3 ）基於改進的bp網路對鄧肯張模型主要參數修正研究。The sand is provided with the pseudo - cohesion c by reinforcement, which verified " the frictional reinforcement theory " and " the pseudo - cohesion theory " ; ( 2 ) the vertical pressure can influent the friction only within certain limits ; ( 3 ) the frictional performances of different filling with the same reinforcement are different ; ( 4 ) when the reinforcement and filling are similar, the development of the friction between reinforcement and filling is influenced by physical state of filling ; ( 5 ) the achievement of experiment are applied to project
砂土加筋后具有較大的準粘聚力c值，這證實了關于加筋土原理中的「摩擦加筋理論」和「準粘聚力理論」 。 （ 2 ）當垂直壓力在一定范圍內時，垂直壓力越大，摩阻力越大；但當垂直壓力超出一定范圍后，其對摩阻力的影響逐漸減弱， f曲線趨于平緩，且似摩擦系數隨垂直壓力的增大呈非線性減小。The sand in taklamakan bo has fine grains with similar diameters, and its strength characteristics are not fully are to ordinary sand as well as silty. but its strength shows some features similar to clay when with some water content
塔克拉瑪干沙漠砂顆粒極細，粒徑均勻，其強度特徵既不完全等同於普通砂，又不同於粉土，在含水狀態下則又表現出與粘性土相類似的特點。
