摘　　要：四川乐山弥勒大佛高 62m ,是现存最大的古代石雕。为了对它作保护 ,需要了解它的内部状况 ,并搞清石雕的现貌及了解地下水的危害。首先用近景立体摄影保留下大佛的现貌 ,并制成立体外貌图及正、侧面“等高线”平面图。然后采用电阻率测深、电阻率剖面、核子密度和湿度仪、声波等物探手段 ,查明了外包层后面的石雕的轮廓、石雕内部的破损点、可能使石像破坏的岩体卸荷裂隙 ,并查明了石雕脸部主要出水点 ,为大佛维护提供了重要的基础资料。Leshan Great Buddha ,62m tall and cut on the cliff, is the biggest ancient stone statue extant in the world. There is a cover made of material of lime, clay and etc. To design protecting work of the Buddha it was required to clearly know its present conditions, near sterephotograph, resistivity survey, nuclear geophysical method and acoustic wave method, which had been used to know the extant condition of the stone inscription, underground water and the outline of stone statue and damages inside it. Good and important results had been got by geophysical survey.
