在大中型水利工程和自然灾害防治工程中,对高边坡及危崖体常采用预应力锚索孔进行锚固处理。预应力锚索孔采用的是二次灌浆法,因此,锚根的注浆质量如果不好,在作预应力处理时.锚索就有可能被拉松或拉出,从而达不到锚固要求。采用微电极系视电阻率电位法对锚根注浆深度实施控制后,有效地避免了事故的再度发生,取得了良好的效果。 In large and medium-sized water conservancy projects and natural disaster prevention and control projects, high slope and dangerous cliff body often prestressed anchor hole for anchoring. Prestressed anchor hole is used in the second grouting method, so the anchor root grouting quality is not good, when prestressed processing, the cable may be pulled or pulled out, so as to reach the anchorage requirements . Using the microelectrode system apparent resistivity potential method to control the depth of anchor root grouting effectively avoid the recurrence of accidents and achieved good results.
