Based on the theory of unsaturated soil mechanics and the properties of compacted expansive soil, this paper takes the northern part k12 + 840 - k12 + 920 of nanning urban highway as an example to studies some aspects of lime improvement of expansive soil and the technology of construction. the chief content of this paper is : the lime improvement mechanism of expansive soil ; confirm the technical parameters of lime mixed from the results of test in laboratory ; the scale - down test to define the maximum effective grain size of expansive soil when it is improved by lime ; by building bank slope model and making use of finite element seepage flow program of saturated - unsaturated to calculate the examples, this paper simulates the humidity site in order to checkout the effect of lime improvement ; studies and proves that it is feasible to mix blocky expansive soil and pulverous lime, and to fill roadbed by common construction machines etc.
本文研究的工作就下述幾個方面展開：用石灰改良膨脹土的機理；通過室內試驗確定摻灰的技術指標；在室內進行膨脹土摻灰的最大有效粒徑的模擬試驗，即鈣離子水試驗，由此總結出「粉?塊」灰?土攪拌工藝的有效性、合理性和可行性；用數值方法對路堤使用期的濕度場進行模擬，並與路堤的強度?變形的計算域耦合，以檢驗土性改良的效果，從而探索一種描述改良膨脹土路堤運行工況的數值方法；用現有最常用的且費用最低的施工機具，對灰?土進行「粉?塊」攪拌摻和及路基的填築施工等。The reference values of strength parameters of the grounds and rock - fillers of the high rock - filled embankment on liuzhai - shuien highway in guangxi are obtained in this paper by synthetically analyzing the construction technology at home and abroad and indoor rock tests. by comparing the analysis method of settlement laws and thoroughly analyzing the datum of the embankment settlements of liuzhai - shuiren highway from the whole cons truction period, a new method generated from expectation technology to analyze the embankment settlement laws, " compete " growth curve, is presented in this paper and the result tallies with the observation data. for there are shortcomings in indoor rock tests, in this paper by combining finite element method with duncan - chang nonlinear constitutive model and composite method, a method for back analysis of the strength parameters of rock fillers is presented with a corresponding program, which has been successfully applied

陜南坡改梯填築土的擊實特性與抗剪強度試驗研究This article mainly emphasize on the classification of coarse grained soil from the viewpoint of engineering application ( content of coarse grains ), vibrating method is introduced in the shaping. meanwhile, research is made to the water stability and shear strength. through research, following conclusions are obtained : coarse grained gradation is the main factors to determine its shear strength, when the coarse grains content is over 70 % or around, the maximum shear strength appears : the grains itself have a bigger effect on the shear strength
以往對粗粒土的研究方法多採用擊實法，很少有人研究其抗剪強度特性，本文主要從工程應用的角度（粗粒含量）對粗粒土進行工程分類，成型方法採用振動法，同時對水穩定性、抗剪強度特性進行研究，通過研究得出以下結論：顆粒組成級配特性是決定其抗剪強度的主要因素，當粗粒含量在70左右時，抗剪強度最大；顆粒本身的特性對抗剪強度影響較大，顆粒越堅硬、大小顆粒相差越大、越不均勻、顆粒形狀越呈稜角狀、填築密度越大，抗剪強度就越高；含水量對抗剪強度的影響很小，可以忽略不計。Based on the in - situ tests of solidified mud casted under water and on land, the strength and deformation of the solidified mud and the bearing capacity of the casting foundation on two casting conditions are compared
