从原料、织造方式、孔径大小、老化等角度对土工织物袋主要参数的选择进行讨论。理论上推导了充泥袋应用在堤坝上的有关计算式,即确定充泥袋间距、周长大小。通过采用等间距和不等间距两种方案的计算比较,说明了采用不等间距铺设方法更经济。同时在不同的土工织物容许抗拉强度T_a情况下,验证袋体的间距、周长、层间稳定系数。同时也推断出随着T_a的增加,可减少铺设层数。
The selection of the main parameters of geotextile bags is discussed from the viewpoints of raw materials, weaving mode, pore size and aging. In theory, the calculation formula of filling mud bag on dykes is deduced, that is to say, the distance and the circumference of filling mud bag are determined. Through the use of equal spacing and unequal spacing between the two programs of comparison, shows that the use of unequal spacing laying method is more economical. In the meantime, under the condition of different allowable tensile strength of geotextile T_a, the spacing, perimeter and interlayer stability coefficient of the bag were verified. It is also deduced that with the increase of T_a, the number of laying layers can be reduced.
