Referring to the achievements of conservation tillage on dry land farming, there is a series of work to be done to develop new tillage techniques to adapt to double cropping system of wheat and maize in shandong province. such work includes controlling the combine traveling along the line, return the stalk to the field after chopped, subsoiling being done in maize ' s growing stage. the advantage of subsoiling is to make the soil inter placed with soft and hard strips, which is good for decreasing runoff and vaporizing, and retaining rain
1 、保護性耕作條件下，普通小麥條播機的播種質量較差，小麥的田間出苗率比傳統耕作低9 . 3 ；保護性耕作小麥冬前地上部分的生長狀況也較傳統耕作小麥差；由於根系的生長條件較為優越，保護性耕作的小麥的根系生長旺盛、分佈廣，越冬後有利於小麥的地上部分生長，大量發生春季分蘗和次生根，幼穗強烈分化，表現出較傳統耕作小麥強的生長優勢，產量提高6左右。 -
As a whole, the research work of this dissertation can be summarized follows : 1. in accordance with my design patent, namely, reinforced earth retaining wall of r c net, and based on the analysis of the work mechanism, failure pattern, bearing capacity and stability of the reinforced earth, a new concept is expounded, namely, the reinforced earth wall which is thought of as a compound structure increase not only c but also ~ in comparison with non - reinforced earth. some bearing capacity formula are first introduced under the circumstances that the reinforced earth wall fails because of the breakage of material or inadequate cohesion between reinforcements and soil
歸納起來，具體的研究和所獲得的一些重要成果如下： 1 、結合本人的設計專利? 「鋼筋混凝土網格式加筋擋墻」及工程實踐，在對加筋土的加筋機理、破壞模式、承載力和穩定性等方面進行深入分析的基礎上，提出了一個新概念，即經過加筋后的土體作為復合結構與原土體相比，不僅提高了內聚力，而且也提高內摩擦角；並在此前提下首次導出拉力破壞和粘著破壞兩種情形下的承載力公式，然後進行了穩定性分析。 -

The top beam can reform the force - bearing mechanism of the retaining piles because the cantilever piles can be fixed by adding a restriction on the top of the piles and the displacement of the piles can be reduced too. as the same time, top beam can harmonize the displacement and force of the piles and avoid the phenomenon of chain failure as one of the piles is destroyed. if the top beam are closed it can work well because the support on the two ends
樁頂圈樑對支護樁的作用主要體現在：改善支護樁的力學性狀，變懸臂樁為頂端約束的超靜定狀態；對樁頂位移起限製作用，減小基坑工程對周邊環境的不良影響；協調各樁之間的受力和位移，避免局部受力過大引起各樁之間的連鎖破壞現象。 -
As a new retaining structure, composite soil nailed wall has been widely applied in the foundation pit now, research on the work performance of the soil nailed wall during the construction can not reveal on - site work, this occurs especially in xi ' an area with rich groundwater where groundwater is forbidden to be lowered
復合土釘墻作為一種新型的擋土結構，目前在基坑工程中得到了較為廣泛的應用，然而對復合土釘墻在施工過程中的工作性能的理論研究卻遠遠落後于工程實踐。尤其在西安地區地下水位較高且不能降水的前提下，當採用復合土釘墻進行基坑支護時，對其工作性能的研究幾乎為零。 -
