In the end , this paper suggests that , the anti - inrushing stability of confined water foundation pit in soft soil area should be analyzed from perviousness and inrushing mechanism of soil at the bottom of the pit
最后分析指出，软土地区承压水基坑抗突涌稳定分析，应从坑底土透水性和土体发生突涌破坏的机理着手。
The result indicated that straw mulching could increase soil porosity by 2 . 88 % - 5 . 76 % , reduce soil bulk density by 1 . 86 % - 3 . 73 % and the content of soil water with straw mulching was higher than that with no straw mulching treatment ( ck1 ) at different growth stage , improve water - stable aggregate ; and increase soil organic matter , available n , available p , available k , improve soil perviousness and soil retention of water and fertilizer
研究结果表明，与对照ck1 ，相比，秸秆覆盖可使土壤总孔隙度增加2 . 88 % ~ 5 . 76 % ，土壤容重降低1 . 86 % ~ 3 . 73 % ，并且各生育期覆盖处理的土城含水量均比对照高，并且秸秆覆盖还田对促进土壤团粒结构形成具有较大作用，改善了土坡通透性和保水保肥性；同时秸秆覆盖还田使土壤有机质、全氮、速效氮、速效磷、速效钾得到明显提高，从而培肥地力。
