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。 -
Now people are adopting the simulation test to resolve this question. and, withal, 1 : 1 scale specimen can be employed in simulation test that can avoid appearing the " distortion " in the scale - down test. in simulation test, the same test can be made times without number and results of test are more full - scale and exact
而且它可以進行1 ： 1的模型試驗，避免出現進行小比例試驗所產生的「失真」現象；它還可以反復多次進行同一個試驗，能夠更加全面觀察模型上所有點的受力情況，能夠更加準確測量出模型的變形和應力。
