Reconnaissance method for quickly determining anti-seepage range of reservoir single watershed
The invention discloses a reconnaissance method for rapidly determining an anti-seepage range of a reservoir thin watershed, and relates to the field of engineering geology and hydrogeological reconnaissance. The method comprises the following steps: step 1, carrying out surface topography and geological surveying and mapping on a watershed range, and finding out the distribution range, material composition, water outlet point positions and surface structure exposure conditions of a covering layer; 2, the critical position of the intersection point of the underground watershed elevation and the normal water storage level elevation is explored; 3, a drilling point ZK2 is arranged in the middle of the bealock; a drilling point ZK1 and a drilling point ZK3 are arranged at the two ends of the bealock respectively; step 4, drilling ZK1, ZK2 and ZK3; and 5, determining the depth of the relative water-resisting layer and the length of the anti-seepage section, and quickly determining the anti-seepage range of the watershed. Holes are distributed purposefully and scientifically, the drilling cost is saved, the exploration period is shortened, the watershed anti-seepage range is rapidly determined, and a geological basis is provided for seepage control engineering design.
本发明公开了一种快速确定水库单薄分水岭防渗范围的勘察方法，涉及工程地质、水文地质勘察领域。它包括以下步骤：步骤1：对分水岭范围进行地表地形、地质测绘，查清覆盖层的分布范围、物质组成、出水点位置、地表构造出露情况；步骤2：探查地下分水岭高程与正常蓄水位高程交点临界位置；步骤3：在垭口中部布置1个钻探点ZK2；垭口两端各布置一个钻探点ZK1、ZK3；步骤4：钻进ZK1、ZK2、ZK3；步骤5：确定相对隔水层深度和防渗段长度，快速确定分水岭防渗范围。本发明有目的性的科学的进行布孔，节省钻探成本，缩短勘探周期，快速确定分水岭防渗范围，为渗控工程设计提供地质依据。
