Abstract: Based on quality evaluation, deformation review and slope stability analysis against sliding of Menlou reservoir main dam, its structural stability was evaluated. The evaluated results showed that the main dam slope stability against sliding could meet the regulatory requirements, the reservoir bank near the main dam was basically stable, but the depression existed at the upstream slope with poor placement quality, and the sand grain material of the upstream dam shell with the potential seismic liquefaction was possibly liquefied soil.

摘要: 在主坝坝体工程质量评价、变形评述、坝坡抗滑稳定分析的基础上,评价了门楼水库主坝的结构稳定性。结果表明:主坝坝坡抗滑稳定满足规范要求,近坝库岸基本稳定,但上游护坡存在凹陷、填筑质量差,且上游坝壳砂砾料存在地震液化的可能。
