摘要
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 paper discusses how to choose raw materials , weaving ways , opening size and aging for geotube . Some formulas are deduced theoretically for use of geotube in dam. Comparing way of equal space with of unequal space , we find the latter is more economical. Under different permitted stress Ta , laid space, circumference, stability index between layers are determined. With Ta increasing, the number of laid layers is decreasing.
