散货堆场深厚软基加固中塑料排水板耐久性的探讨

对于铁矿石、煤炭等散货堆场深厚软基加固,采用塑料排水板和使用期分级加载方案时,其时间跨度大,应考虑塑料排水板的排水性能耐久性问题,以确保加载期间塑料排水板的排水性能.使实际的地基排水固结状况符合设计计算模型.通过对不同塑料排水板材质、结构、生产工艺的对比,分析了塑料排水板耐久性的影响因素.提出在散货堆场软基加固中,当时间跨度大时应采用耐久性塑料排水板的观点.

On durability of plastic drainage belt during consolidation treatment of deep soft ground for bulk cargo yard

For deep soft ground reinforcement by plastic drainage belt and when loaded by stage,since the construction period is long,the durability of plastic drain belt must be considered,so as to ensure its drainage efficiency during loading period and ensure the consolidation effect.Based on the comparison of material,structure,production process of different plastic drainage belts,the impact factors of drainage durability are analyzed and some views are proposed that the high-performance plastic drainage belt should be used in the reinforcement of soft ground for bulk cargo yard when the time span is large.
