    • Abstract
  • Geomembrane tubes have been widely used to construct dikes, rubber dams and flood control structures. The analytical methods for the design of geomembrane tubes have been well developed. However, these methods cannot be used directly but have to operate using computer program. For the convenience of research and design, a curve fitting method is proposed to simplify the design process for the geomembrane tubes. The pumping pressure, tensile force and geometric parameters are dimensionless. Based on the computer program, the relation curves among the pumping pressure, tensile force and geometric parameters of geomembrane tubes are established. A set of simplified dimensionless design equations are then derived using the Chapman-Richard model. The validities of these curve fitting equations are verified using the results by others and large scale laboratory model tests. The proposed curve fitting equations can be used for the preliminary design of the geomembrane tube.
