| 对土工建筑物护坡的经常性养护和破坏后的修理工作。护坡是土工建筑物外部结构的重要组成部分，对土坝、土堤、土渠的主体起保护作用。土工建筑物护坡有迎水、背水两面。迎水面护坡采用自土体顶部直至底脚或至死水位以下某深度全面护砌的办法，所用材料和形式有干砌石、堆石、浆砌石、混凝土和沥青渣油混凝土等类，常用的是干砌块石护坡。背水面护坡常采用草皮、卵石、碎石或块石护砌。 The regular maintenance of the slope protection of the geotechnical structure and the repair work after the damage. Slope protection is an important part of the external structure of the earth structure, which plays a protective role in the main body of earth dam, earth dike and earth canal. The slope protection of geotechnical structures has two sides of facing water and back water. The method of comprehensive protection from the top of soil to the foot or to a certain depth below the dead water level is adopted for the upstream slope protection. The materials and forms used include dry masonry, rockfill, mortar masonry, concrete and asphalt residue concrete, etc., and the dry masonry slope protection is commonly used. Turf, pebble, gravel or block stone are often used for slope protection of back water surface. 破坏原因 大量的破坏是由于受风浪冲击、块石撞击和冰冻、强烈震动与爆破等外力作用，再加以有的护坡本身结构设计不合理、施工质量差、选取的材质低劣或运用管理不当，牲畜践踏，草木丛生等。 A large number of damage causes are caused by the impact of wind and waves, block stone impact and freezing, strong vibration and blasting and other external forces, and then some revetments have unreasonable structural design, poor construction quality, poor selection of materials or improper use and management, livestock trampling, vegetation, etc. |
