绿滨垫防护一般规定：
1、绿滨垫可简单铺设于需要防护的岸坡上，土坡的坡比不宜大于1：1.5，砂质土坡坡比不宜大于1：2.0。
2、采用绿滨垫护坡时，应确保边坡自身稳定，并应将护坡基础埋置到较大冲刷深度以下。不设护脚时，防护范围应向河床中延伸至1.5倍～2.0倍的较大冲刷深度，或采用绿滨垫对河床全断面防护。
3、为增加护坡侧缘的强度，绿滨垫在上游和下游边界处应加厚。
4、绿滨垫应分成格室，隔片间距应小于或等于1m。
5、绿滨垫下宜铺设一层土工布或100mm～150mm厚砂砾石层作为反滤层。
6、护坡设计高度具体计算可按现行国家标准《堤防工程设计规范》GB?50286执行。
7、?寒区采用冰上沉排施工绿滨护坡时，绿滨垫应形成整体，并应满足下沉过程中的强度和变形要求。
Green shore cushion protective general provisions:
1, simple green shore mat can be laid in need of protection on bank slope, soil slope ratio should not be greater than 1:1. 5, sandy soil slope ratio should not be greater than 1:2. 0.
2, adopt green shore slope protection, shall ensure that its slope stability, and slope protection foundation embedment should be below the maximum scour depth.No spats, protection range should be extended to the riverbed and 1.5 ~ 2.0 times of the maximum scour depth, or whole section adopt green shore pad for bed protection.
3, to increase the strength of the cephalic margins of the slope protection, green shore pad should be upset at the upstream and downstream boundaries.
4, green shore pad should be divided into lattice room, spacer spacing should be less than or equal to 1 m.
5, green appropriate laid a layer of geotextile under pad or 100 mm to 150 mm thick gravel stone layer as a filter layer.
6, height of slope protection design calculation according to the current national standard "specification of levee project design" GB 50286 is carried out.
7, cold and heavy line construction using the ice green shore slope protection, green shore pad should be formed as a whole, and shall meet the requirements of strength and deformation in the process of subsidence.
