介绍红石岩堰塞体及堰塞体坝基工程地质特性。分别对堰塞体与堰塞体坝基进行了变形稳定性,渗漏、渗透变形分析。研究表明堰塞体渗透性、变形稳定性均较小,仅堰塞体表层和堰塞体坝基存在一定的渗漏问题,有发生渗透变形破坏的可能,故建议河床冲积层、古滑坡体、古河床冲积层正常蓄水位以下进行全断面防渗。
介紹紅石巖堰塞體及堰塞體壩基工程地質特性。分彆對堰塞體與堰塞體壩基進行瞭變形穩定性,滲漏、滲透變形分析。研究錶明堰塞體滲透性、變形穩定性均較小,僅堰塞體錶層和堰塞體壩基存在一定的滲漏問題,有髮生滲透變形破壞的可能,故建議河床遲積層、古滑坡體、古河床遲積層正常蓄水位以下進行全斷麵防滲。

The paper gives an introduction to the engineering geological features of Hongshiyan landslide dam and its foundation and analyzes deformation stability, leakage and seepage deformation of both landslide dam and its foundation respectively. The study indicates that the permeability and the deformation stability of the landslide dam are both unremarkable, and only the surface of the landslide dam and its foundation have certain leakage problem, which is possible to cause seepage deformation damage. Therefore it is recommended to take full-section seepage control measures for the river bed alluvium, the ancient landslide body and the ancient river bed alluvium below the normal storage water level..
