经幢形瘗龛在南充市共发现 4 龛，其中大像山石窟 3 龛，白山崖墓 1 龛，皆开凿于宋代，这 4龛中的方形穴主要用于放置佛教信众的骨殖。大像山石窟第 18 龛主要依据佛陀波利译《佛顶尊胜陀罗尼经》雕凿，幢身仅刻咒语，除与刻经时代风气日趋简略相关外，还与经幢的高度和面数，及与咒语的重要功能有较大关系。经幢形瘗龛的出现与当时地狱信仰的盛行、《佛顶尊胜陀罗尼经》的破地狱功能及功能分区与墓幢的使用息息相关。

A total of 4 stupa-shaped burial niches have been discovered in Nanchong City, three in the Daxiangshan Grottoes and one in the Baishan Cliff Tombs, all dating to the Song Dynasty. The square recesses in these niches were mainly used for placing the remains of Buddhist devotees. The 18th niche in the Daxiangshan Grottoes was primarily built according to the Buddhosnisa Vijaya Dharani Sutra translated by Buddhapala. The body of the stupa was only engraved with mantras. This resulted not only from the trend toward simplification in sutra inscription at the time, but also from the height and number of sides of the stupa, as well as the important function of the mantras. The appearance of stupa-shaped burial niches is closely related to the prevalence of the hell belief at the time, the sutra’s role in breaking through hell, the functional zoning, and the use of funerary stupas.
