| 摘 要： | 0引言
风积沙土沿黄河两岸分布，地下水位较高，塑性指数小，渗透性较好，含水量较大。桥涵的基础部分或全部处于地下水位线以下，为保证干法作业，应做好降水处理。

Dewatering Technology for Bridges and Culverts on Wind-blown Soil |
| |
| Abstract: | The wind-blown soil spreading along the shores of Yellow River,is of high ground water level,small plasticity index,obvious penetrability and substantial water content.For those bridges and culverts whose foundations are lower than phreatic line,a measure should be conducted to lower the water level.The wellpointing can effectively prevent drift sand, making sure the side slopes are stabilized. |
