[中英]提高路基及路面基層平整度的措施

　　路基的施工質(zhì)量，是整個(gè)路線工程的關(guān)鍵，也是路基路面工程能否經(jīng)受住時(shí)間、車輛運(yùn)行荷載、雨季冬季的考驗(yàn)。要做好路基工程，必須扎扎實(shí)實(shí)地進(jìn)行路基的填筑，尤其對原地面的處理和坡面基地的處理?！　÷返烫盍弦话銘?yīng)采用砂礫及塑性指數(shù)和含水量符合規(guī)范的土，不使用淤泥、沼澤土、凍土、有機(jī)土、含草皮土、生活垃圾及含腐殖質(zhì)的土。對于液限大于50，塑性指數(shù)大于26 的土，一般不宜作為路基填土，但在安藺段，由于費(fèi)用和當(dāng)?shù)赝临|(zhì)的原因，受工程作業(yè)現(xiàn)場條件限制，必須使用。　　The roadbed construction quality, the whole line is the key, but also the road embankment project can be withstood time, vehicle running load, the test of the winter rainy season. Roadbed project to do, we must earnestly carry out the roadbed filling, in particular, the original ground handling and processing base of the slope.　　General embankment fill gravel and plastic should be used for compliance and the soil moisture content, the non-use of mud, swamp soil, frozen soil, organic soil, soil with grass, garbage and the soil with humus. For more than 50 liquid, plastic index greater than 26 territories, the general should not be as roadbed fill, but in the rush, the local soil and because of the cost of reasons, the works site constraints, must be used.
