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。 -
We made an improvement in overcoming the defects in speech signal adaptive delta modulation ( abbr. adm ), such as slope overloading and grain noise. in this method, numerical sliding average filtering was used for filtering decoding speech signal. experiments and analyses indicate that the method makes waveforms in good agreement between the decoding of adm and the original pulse coding modulation ( abbr. pcm ) signal, and considerably improves, the playback speech quality in naturalness, legibility and under standability
針對語音信號自適應增量調制（ adm ）方式中斜率過載和顆粒噪聲缺點，提出了一種改進方法，它利用滑動平均方法對解碼后的信號進行數字濾波.試驗和分析表明，該方法使解碼后的信號波形與原脈沖編碼調制（ pcm ）波形具有很好的一致性，使再生語音質量在自然度、清晰度和可懂度方面比改進前均有較大提高 -
A systematic study is conducted on engineering behaviors of residual soil, failure mechanism of residual soil slope and mechanism of natural flow slides triggered by rainstorm in jiang jia drainage area. to investigate engineering properties of disturbed soils, a series of tests, including grain - size analyses, permeability tests, direct shear tests and dynamic iriaxial lest is performed on specimens
本文在總結熱帶坡殘積土地區暴雨滑坡轉化成泥石流的研究現狀和進展的基礎上，對雲南東川市蔣家溝地區坡殘積土的工程特性、暴雨條件下斜坡土體的破壞機理、暴雨滑坡轉化成泥石流的形成機理和形成過程進行了較為系統的研究。 -
First, total resistance is derived by summing different resistance components. the relationship between resistance of still plane bed and energy slope has been proposed from the similarity between sediment incipient motion and still bed resistance. and this relationship can be used in computing grain resistance
一是從不同的床面阻力單元出發，利用泥沙起動與定床阻力之間的相似性研究了靜平整床面的阻力，建立了靜平整床面阻力與能坡之間的關系式，並將此式用於沙粒阻力的計算。
