土工材料處理軟土路基的要求: Geotechnical material handling soft soil subgrade requirements:   1)土工材料應由耐高溫、耐腐蝕、抗老化、不易斷裂的聚合物材料制成。其抗拉強度、頂破強度、負荷延伸率等均應符合設計及有關產品質量標準的要求。 1) geotechnical material should be high temperature resistant, corrosion resistant, anti-aging, not easy fracture of polymer materials. Its tensile strength, bursting strength, and elongation of load shall conform to the requirements of design and the product quality standard.   2)土工材料鋪設前,應對基面壓實整平。宜在原地基上鋪設一層30~50cm厚的砂墊層。鋪設土工材料后,運、鋪料等施工機具不得在其上直接行走。 2) geotechnical material before laying, base compaction leveling. Should be laid on the original foundation a 30 ~ 50 cm thick layer of sand cushion. After laying geotextile materials, charging construction machinery such as shop, not directly to walk.   3)每壓實層的壓實度、平整度經檢驗合格后,方可于其上設鋪土工材料。土工材料應完好,發生破損應及時修補或更換。 3) each layer compaction compaction and smoothness after inspection, spread geotechnical material shall be set on it. Geotechnical material should be in good condition, damage shall promptly repair or replacement.   4)鋪設土工材料時,應將其沿垂直于路軸線展開,并視填土層厚度選用符合要求的錨固釘固定、拉直,不得出現扭曲、折皺等現象。土工材料縱向搭接寬度不得小于30cm,采用錨接其搭接寬度不得小于15cm,采用膠結其膠接寬度不得小于5cm,膠結強度不得低于土工材料的抗拉強度。相鄰土工材料橫向搭接寬度不得小于30cm. 4) laying geotextile materials, should be along the perpendicular to the axis of the road, and fill in the soil layer anchor nail selection to meet the requirements, straighten, may not appear the phenomenon such as distortion, crease. Geotextile materials longitudinal lap width should not be less than 30 cm, USES the anchor to the width of the lap joint shall not be less than 15 cm, using cementing the glue joint width shall not be less than 5 cm, cementing strength shall not be less than tensile strength of the geotechnical materials. Adjacent geotechnical material horizontally overlapping width should not be less than 30 cm.
