土工织物充填管袋是土工包裹系统的一种,它用编织土工布缝合而成,再用高压泥浆泵充填砂浆,最终形成管状袋体,优点众多,可用于堤坝填筑、抗洪抢险等工程中,应用前景广阔。但目前关于土工管袋形状、高度、张力等参数的计算方法主要是针对高充填压力情况的,而中国实际工程中较多的是充填压力较低即袋体扁平的情况,因此针对目前研究的不足,提出现有无量纲计算方法的适用条件,并对其进行改进,提出低充填压力下的袋体特性计算方法并进行验证,计算结果被制成图表,方便实际应用时查找参数。
Geotextile filled tube bag is a kind of geotextile package system. It is made of woven geotextile and then mortar is filled with high pressure mud pump to form tubular bag body. It has many advantages and can be used in the construction of levees and dams, flood control and rescue work , Broad application prospects. However, at present, the calculation methods for the shape, height, tension and other parameters of geotextile bags are mainly for high filling pressures. However, in China, the more filling pressure is, the lower the filling pressure is. Therefore, This paper puts forward the calculation method of bag body under low filling pressure and verifies it. The calculation result is made into a chart, which is convenient to find the parameter in practical application.
