为解决某堤防工程排水管幕工程渗流问题,提出9种排水管幕布置方案,并采用改进子结构法模拟该工程排水管幕,首先建立岸坡结构三维有限元模型;其次分析岸坡浸润面形态及排水效果;最后综合考虑经济及排水效果等因素提出相应的满足不同侧重面的排水管幕布置方案。研究结果表明,若侧重于排水效果,选择方案7;若兼顾排水效果及经济,选择方案8;若侧重经济且兼顾排水效果,选择方案1;本工程排水管幕布置选择方案7,该方案已运用于除险加固工程中,取得良好的效果。研究结果为解决相关工程的渗流问题提供技术支持。
In order to solve the problem of seepage of the drainage curtain works in a dike project, nine kinds of drainage pipe curtain layout schemes were put forward and the sub-structure method was used to simulate the drainage pipe curtain. First, a three-dimensional finite element model of bank structure was established. Secondly, Morphology and drainage effect; finally considering the economic and drainage effects and other factors to put forward corresponding to meet the different layout of the drainage pipe curtain plan. The results show that, if the emphasis is on drainage effect, choose Scheme 7; if both drainage effect and economy, choose Scheme 8; if economic focus and take into account drainage effect, choose Scheme 1; Used in reinforcement projects, and achieved good results. The results provide technical support for solving the seepage problem of related projects.
