摘要
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 tube is one kind of the geotechnical package system. It is made of woven fabric, filled with the mortar by high-pressure mud pump, and eventually becomes a tube. The geotextile tube has many advantages and wide application prospects, and it can be used for building dams and flood prevention projects. The existing theoretical calculation methods have good applicability to calculate the shape, height, tension and other parameters of geotextile tubes under the situation of high filling pressure. However, they are not suitable for the situation of low filling pressure. As the geotextile tube applied in China is often flat, and the filling pressure is low. The applicable conditions of the current dimensionless method are proposed, and the method is proved to calculate the parameters of the geotextile tube with low filling pressure. The equations are solved by numerical integration, and the results are verified and formed into charts. Thus it is easily to find the value of the parameters in actual applications.
