【摘要】 根据我们编制水土保持方案的工作实践,对借土场和弃渣场分别进行了分类:借土场可分为沿等高线借土、不跨山脊坡面借土和跨山脊坡面借土三大类;弃渣可分为填洼(塘)弃渣、沟道弃渣、坡面弃渣和平地弃渣四大类。提出了借土场和弃渣场的优先选择方法:借土方式应优先选择沿等高线借土,跨山脊坡面借土次之,最后考虑不跨山脊坡面借土;弃渣方式应优先选择填洼(塘)弃渣,平地弃渣次之,最后选择沟道弃渣或坡面弃渣。根据借土场、弃渣场类型的不同,合理布设了综合防护措施。更多还原

【Abstract】 Based on the practical work of compiling scheme for water and soil protection,classification on soil pits and residue pits were made out.For soil pits,there were three categories:soil digging along contour line,soil digging at slope without striding over ridge,soil digging at slope bestriding ridge;and the residue pits were classified into four categories:low-lying (ponds),ditch,slope and flat pit.The preference soil pit was contour line pit,the second choice was soil digging at slope bestriding ridge,and the last selection was soil digging at slope without striding over ridge.And the preference residue pit was low-lying(pond),next was flat pit,and the last choice was ditch or slope pits.Different layouts and comprehensive control measures were point out in terms of different kinds of soil pits and residue pits.更多还原
