摘　　要：以新疆地区高地下水位、盐渍土、冻胀等条件下的某新建机场工程为例,设计了一种典型地下水处治方案,并经Visual Modflow软件建模验证:高地下水位时,机场地势设计对整体地形起伏不大地区的地下水渗流场有一定影响,但影响范围有限,影响幅度不大。可通过合理的地势设计、透水型截排水沟布置,大幅降低相应位置的地下水位,达到设计目标。采用防、排、疏、降相结合的综合治水措施,创新性地设计出了一种防冻胀并透水、耐冲刷,适应变形并维持稳定,节省造价、无需停航并易于检修的截排水沟型式,目前工程运行良好。Taking a newly built airport project in Xinjiang region under conditions such as high groundwater level,saline soil,and frost heave as an example,a typical groundwater treatment plan was designed and verified through Visual Modflow software modeling:when the groundwater level is high,the airport topographic design has a certain impact on the groundwater flow field,but the scope of influence is limited and the amplitude of influence is not significant.By designing reasonable terrain and arranging permeable intercepting/drainage ditches,the groundwater level at corresponding locations can be significantly reduced to achieve design goals.A comprehensive water control measure combining prevention,drainage,transport,and dewatering has been adopted to innovatively design a type of intercepting/drainage ditch that is resistant to frost-heaving,permeability,erosion resistance,adapting to deformation,keeping stability,cost saving,and easy maintenance without the need for suspension of navigation.Currently,the project is operating well.
