柔性填埋场与刚性填埋场不同之处 Differences between flexible landfill and rigid landfill

柔性填埋场：采用双人工垫层（一般采用两层HDPE土工膜）作为防渗层的填埋处置设施，一般用在地质条件较好、地下水位较低的区域。

Flexible landfill: A landfill disposal facility that uses a double layer artificial cushion layer (usually two layers of HDPE geomembrane) as the anti-seepage layer, usually used in areas with good geological conditions and low groundwater levels.

主要设计要点：柔性填埋场应采用双人工复合垫层作为防渗层。

Main design points: The flexible landfill should use a double artificial composite cushion layer as the anti-seepage layer.

1、主衬层应具有厚度不小于0.3m,且其被压实、人工改性等措施后的饱和渗透系数小于1.0*10-7cm/s的粘土衬层。

1. The main lining layer should have a thickness of no less than 0.3m and a clay lining layer with a saturated permeability coefficient of less than 1.0 * 10-7cm/s after compaction, manual modification, and other measures.

2、次衬层应具有厚度不小于0.5m，且其被压实、人工改性等措施后的饱和渗透系数小于1.0*10-7cm/s的粘土衬层。

2. The secondary lining layer should have a thickness of no less than 0.5m and a clay lining layer with a saturated permeability coefficient of less than 1.0 * 10-7cm/s after compaction, manual modification, and other measures.

3、采用高密度聚乙烯（HDPE）作为人工合成防渗材料时，其厚度不小于2.0mm。

3. When high-density polyethylene (HDPE) is used as an artificial synthetic anti-seepage material, its thickness shall not be less than 2.0mm.

4、柔性填埋场应设置两层人工复合衬层之间的渗漏检测层。

4. A leakage detection layer should be installed between two layers of artificial composite lining in a flexible landfill.

刚性填埋场：采用钢筋混凝土结构作为防渗层的填埋处置设施，一般用在软土区、地下水水位较高的区域。

Rigid landfill: A landfill disposal facility that uses a reinforced concrete structure as an anti-seepage layer, usually used in soft soil areas and areas with high groundwater levels.

主要设计要点：钢筋混凝土结构应内衬人工防渗衬层。

Main design points: The reinforced concrete structure should be lined with an artificial anti-seepage lining layer.

1、混凝土抗压强度不低于25N/mm2，厚度不小于35cm.

1. The compressive strength of concrete shall not be less than 25N/mm2, and the thickness shall not be less than 35cm

2、设计成若干独立对称的填埋单元，每个填埋单元面积不得超过50m2或容积不得超过250m3.

2. Designed as several independent and symmetrical landfill units, each with an area not exceeding 50m2 or a volume not exceeding 250m3

3、应设置雨棚和目视检测层。

3. Canopy and visual inspection layer should be set up.
