compacted fill
解釋
壓實填土-
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。 -
Based on the roller - compacted test, check on construction and observation during operation, the fill - criteria of the design for the dam is obtained, and then the economic and reasonable roller compacted method, including selection of the roller, mechanical parameters, watering amount for material of sandy gravel etc., is determined as well
摘要通過碾壓試驗、施工復核及大壩運行觀測，得到了大壩的設計填築標準，從而確定了經濟合理的壓實方法，包括壓實機械選型、機械參數、砂礫料加水量等。 -
The study provides basic detection theory and practicel engineering experiences for popalarizing surface wave velocity method to detect dry density of compacted rock - fill layer in practice
本項試驗為推廣應用穩態面波法檢測干密度值提供了理論依據和工程實踐經驗。 -
This is the first time to apply prestressed carbon fiber to roadbed engineer in the world. the high tensile strength and corrosion - resisting property of prestressed carbon fiber make it possible that the soil is in triaxial state of stress. therefore, the embankment fill can be compacted, the settlement can be reduced and side slope stability can be improved
本課題第一次將預應力碳纖維技術應用於路基工程中，利用碳纖維的高抗拉強度和高耐腐蝕性，對其施加預應力，使路基土體處於三向受壓應力狀態中，從而加強路堤填料的密實程度、減少路堤的總沉降、增加邊坡的穩定性。 -
The results from regression analysis show : there exists good linear correlation between surface wave velocity and dry density detected at same place of compacted rock - fill layer, so a correlation equation may be established
檢測成果的回歸分析表明：同一種壩料的面波波速與干密度之間具有良好的線性相關性，可建立相關方程。
