| 在双层潜在滑面的岩质滑坡地质灾害治理中，前人欠缺此类治理措施，需要对其寻求一种治理方式。本文以北京延庆区一处潜在的双层软弱带的岩质滑坡为例，研究治理潜在双层滑面且破碎岩质的滑坡处理方法。该滑坡目前浅部滑面已出现位移，深部滑面在监测后未出现位移，其滑体又为极破碎的白云岩，内夹易软化的页岩。因此，需要对浅部和深部两个页岩软弱带采取治理措施。在滑坡治理案例中，存在双层滑面且破碎程度高的滑体的情况极为少见。针对此情况此类滑坡，治理方式采用锚索格构梁对浅层滑面上部滑体锚固，抵消剩余下滑力，同时提高破碎岩体的整体性；利用桩板式挡墙对深层滑面进行稳固，提高其位移时的初始抗滑力。此方式不仅能有效治理浅层滑面，还能有效预防深层滑面产生初始位移。 |

| In the geological disaster control of rock landslide with double-layer potential sliding surface， there is a lack of such control measures before， so it is necessary to seek a control method. In this paper， a rock landslide with a potential double-layer weak zone in Yanqing District of Beijing is taken as an example to study the treatment method of landslide with potential double-layer sliding surface and broken rock. At present， the shallow sliding surface of the landslide has been dislocated， while the deep sliding surface has not been dislocated after monitoring. The sliding body of the landslide is also extremely broken dolomite with soft shale inside. Therefore， it is necessary to take treatment measures for shallow and deep shale weak zones. In the case of landslide treatment， it is very rare to find a double-layer sliding surface with a high degree of breakage. For this kind of landslide， cable lattice beam is used to anchor the sliding body on the shallow sliding surface to offset the residual sliding force and improve the integrity of the fractured rock mass. The pile plate retaining wall is used to stabilize the deep sliding surface and improve its initial anti-sliding force during displacement. This method can not only effectively control the shallow sliding surface， but also effectively prevent the initial displacement of the deep sliding surface. |
