| 摘 要： | 在古建筑石构件不同深度岩样化学成分和矿物成分测试的基础上,对根据不同深度岩样化学成分及矿物
成分的变化来确定风化深度的方法进行了深入研究。结果表明:由于岩石成岩之初其矿物成分和化学成分在不
同部位存在差异,风化后矿物成分和化学成分随深度的变化不具规律性,提出根据化学风化指数沿深度的变化
来确定石构件化学风化深度的方法。实践证明这一方法能较准确地获得石构件的化学风化深度。

| Abstract: | Based on the mineral component and chemical composition test of rock examples from different depths
in an ancient building, this paper studied the conventional method determining weathering depth according to the
change of mineral component and chemical composition of rock examples in different depths. The result indicates
that the change of mineral component and chemical composition of weathered rock with depth is ruleless because
there is difference in the mineral component and chemical composition in different positions of this rock at the
beginning of diagenesis. Thus, the conventional method determining weathering depth according to the relation of
single mineral component or chemical composition with depth will became inapplicable. This paper presented a
new method for determining weathering depth aiming at above condition, which determines weathering depth
from the relation of chemical weathering indices with depth. Practice proves that this method presented can get
accurate chemical weathering depth of ancient stone carving, grotto and rock component of building. |
