摘要

摘要: 近年山区城市通过高填方工程扩展城市空间的实例越来越多,关于填方后地下水位的变化一直备受关注。以陕西某高填方工程为依托,对填方场地工后15个月里地下水位、填筑土体含水率的变化进行了持续的监测。监测结果表明填方后主沟下游地下水位上升幅度明显大于两侧支沟达到1.3 m。主沟下游位置地下15 m以下的深层填土含水率随着深度递增。黄土沟壑高填方工程中主沟位置的地下水排导措施应进一步加强,防止地下水位持续上升,主沟下游位置进行工程建设时应考虑深层填土含水率增加带来的不利影响。

Abstract: In recent years, the construction space of some cities in mountainous areas has been expanded by high fill projects, and the change of groundwater level after filling has attracted much attention. On the basis of a high fill project in Shaanxi, the groundwater level and the change of water content of soils in filling site are monitored continuously. The monitoring results show that the rise of the groundwater level at the lower reaches of the main channel after filling is obviously larger than that of the minor channel, and the maximum value is about 1.3 m. At the downstream position of the main channel, the water content of the deep fill increases with the depth. The measures for the main groove of loess gully high embankment in the groundwater drainage should be further strengthened to prevent the rise of groundwater level, and the construction at the downstream position of the main channel should be cautious considering the adverse effects of the increasing rate of water content of deep soils.
