本論文通過拉鏈式塑料管大氣、土壤中的滲流試驗研究，以及在大棚蔬菜（番茄）栽培應用拉鏈式塑料管滲灌的試驗研究，希望為保護地蔬菜栽培灌水方法的革新和滲灌灌水技術的發展、拉鏈式塑料管作為滲灌管的可行性和優越性提供理論依據。Using fem ( finite element method ), the paper makes mechanical analyses on bench cut method and side heading method, it also makes mechanical analyses on some auxiliary construction methods, such as big pipe - roof protection, horizontal roll - spraying, big and small angle pipe - roof protection and surface grouting
論文採用有限元的分析方法，主要對臺階法、側壁導坑法進行了力學分析，也選擇了大管棚法、水平旋噴法、大小外插角管棚法和地表注漿加固四種輔助工法進行力學分析。It is one of the best water - saving irrigation methods that can save water in the highest degree for such advantages as saving water, saving energy, increasing production, raising air temperature and ground temperature inside the shelf, lowering air humidity inside the shelf, decreasing plight and reducing the use of pesticide and chemical fertilizer, etc. but percolation irrigation is far from a ripe irrigation method for the problems existing in the development of pipes for pi and the two difficult problems which hamper the development of pi ( one is the low uniformity degree irrigation, the other is the blockage in percolation irrigation pipes )
它是迄今為止最節水的一種灌水方法，具有省水、節能、增產、提高棚室空氣溫度和地溫、降低棚室空氣濕度、減少病蟲害、少施農藥和化肥等優點。但滲灌還不是一種成熟的灌水方法，滲灌的發展，首先取決于滲灌管的研製；其次是阻礙滲灌發展的兩大難題：滲灌的灌水均勻度和滲灌管的堵塞兩大難題的解決與控制。This paper presents the application technique of large steel - pipe - shed for dealing with collapse of tunnel combining the treatment practice of a tunnel collapse
