Further Study on Calculating Method of Piping Leakage
-
摘要: 堤防工程在洪水期间发生渗流管涌而形成的险工往往占堤防重点险工的三分之二以上。将管涌产生初期涌水点附近透水层看作是各向同性均质,并利用地下水井流理论,推求出了管涌形成后的出水流量、临界面及破坏界面孔口尺寸的计算公式,并将计算成果与工程实际进行了比较,获得了令人满意的相关效果。Abstract: In the initial stage of piping, looking the permeable nearby piping site as isotropy and homogineous, deducing a formula by the theory of well flow, which can calculate the volume of flow and the areas of critical surface and destroy surface. On the basis of analyzition and comparation, this formula's feasibility is proved.
