摘　　要：岩体工程具有加载和卸荷两类不同性质的力学状态，在此力学状态各异的情况下，节理岩体的力学特性有本质的区别。岩体高边坡工程的力学状态主要为卸荷。在三峡工程永久船闸陡高边坡的研究中，作者提出了“各向异性卸荷岩体力学的新概念”，得出了与目前常规岩体力学研究不同的结论。该研究成果已被多项边坡工程和地下工程实例所验证。以前应用该理论对三峡永久船闸陡高边坡的研究成果，也日益为现监测资料所验证。Owing to the different mechanics conditions of rock mass engineering under loading and unloading, there are essential distinctions between the mechanics properties of rock masses. The mechanics condition of rock slope engineering is mainly unloading with enough ground stress releasing. The anisotropic unloading rock mass mechanics, a new concept in geo-technipues. is put forward by the author in study of the steep-high rock slope of the Three Gorges Project shiplock, and has different conclusion from current rock mass mechanics. The anisotropic unloading rock mass mechanics has been initially testified by variety of rock mass slopes and underground projects, also rock mass of the Three Gorges Project shiplock.
