摘　　要：国道213线郎木寺至川主寺公路改建工程通过我国最大的高原湿地——若尔盖湿地,设计中掌握公路附近湿地的地下水流特征才能确定盲管的管径和铺设密度。为此,在对郎川公路和若尔盖湿地资料收集和实地调查的基础上,通过在典型地区进行抽水试验获得实测数据,并采用数值模拟得到地下水流模型,从而进行盲管排水系统设计。The rebuild project of the National Road 213 Line from Langmusi Temple to Chuanzhusi Temple passes the biggest plateau wetland in our country wetlands in the Zoige plateau. To protect the ecosystem environment of the wetlands and reduce the separation function to the groundwater flows by the highway, it needs to drain water through blind pipes laid in roadbed. To determine the blind pipes＇ diameter and distributable density,it needs to know the characteristic of underground hydrology. Therefore, based on the data collections and on-site inspections, we obtained data by pumping water experiment in the typical model region, established a groundwater flow model by numerical simulation method and then finished the blind pipe drainage system design. This is the first time in the domestic research.
