  1. In the light of its special property being not easy to gain strength, through mechanics researches on different methods to stabilize this kind of low _ liquid _ limit silty soil as subbase material, evaluated both technically and economically, we have got a cement lime stabilization plan to meet the index requirements for non _ side _ limit strength of compression of subbase of class2 road stipulated in the specification ; by means of improving the workmanship, thickening the loose layer of soil, adding soil on covering weave fabric before compaction, such problems can be solved as very poor compaction, loose surface during compaction, roughness and unevenness, coats of layer and shear damages

    本文針對黃河沖積而成的低液限粉土其粘粒含量極低、土的不均勻系數很小、膠體活性差的工程特性,通過採用不同方法穩定該類土作底基層材料的力學性能研究,從技術、經濟角度綜合評價,得到滿足規范抗壓強度指標要求的水泥石灰穩定方案。通過對原材料、試驗配合比設計、施工、等方面進行優化,從而顯著減輕了基層的早期及長期縮裂程度,從而提高了路面的耐久性。
  2. Conclusions as following have got through test study : ( 1 ) when impact compaction technology is applied to treat collapsible loess subgrade, the effect depth may be treated generally can not override 80 cm and impact compaction pass is optimum at 30 times. ( 2 ) for stratified impact compaction of subgrade, when compactness of each level reaches codeslstandards loose laying depth of 80 cm fits 40 impact compaction pass is the optimum combination of subgrade construction. when average compactness in each level reaches codeslstandards loose laying depth of 80 cm fits 30 impact compaction pass is the optimum combination o ( 3 ) the quality control method may request impact compaction pass as the main control index and at the same time the final division settlement is less than 10 % of total settlement as large area subgrade is constructed

    通過試驗研究主要得出如下認識:沖擊壓實技術處理濕陷性黃土地基時,其有效處理深度一般不超過80cm ,沖壓遍數以30遍左右為宜;對路基分層沖壓,在要求土體中各點壓實度均達到規范要求時,路基沖壓最佳組合為虛鋪厚度80cm 、沖壓40遍;在只要求土體平均壓實度達到規范要求時,路基沖壓最佳組合為虛鋪厚度80cm 、沖壓30遍;大面積施工時,質量控制方法可按照在以沖壓遍數作為主要控制指標的同時,要求最後10遍分計沉降量小於累計沉降量10 ;在施工單位自己購置沖擊壓實機情況下,與傳統施工相比較,沖擊壓實技術是一種既能節約資金又能大量縮短工期的施工方法。
  3. Preparation for construction : the surface of the under layer should be even and firm, and in accordance with the design requirement, without loose material and flaccid site, and need to reroll 2 3 times within full - width range of the subgrade with vibrating roller before the construction, as well as test the compaction and defecting, to check whether there is unqualified point in the soil base

    施工準備:施工前下承層表面要平整、堅實,符合設計要求,無鬆散材料和軟弱地點,施工前要用振動壓路機在路基全寬范圍內復壓2 3遍,同時進行壓實度及彎沉檢驗,檢查土基中是否有不合格點。
