三峡太平溪坝址的风化岩体划分为全、强、弱、微四带。坝段内圈划了数处深风化槽。近来研究它们的工程地质特征时,将弱风化岩体分为上部和下部。其下部的特征与微风化岩体很接近,工程地质性状较好,常是深风化槽的主要组成部分。本文仅谈谈我们圈划深风化槽的粗浅认识。 The weathered rock mass of the Taipingxi dam site in the Three Gorges area is divided into four zones: full, strong, weak and micro-four zones. The inner section of the dam draws several deep weathered troughs. In recent studies of their engineering geology, weakly weathered rocks are divided into upper and lower parts. Its lower part is very close to the micro-weathered rock mass, with good engineering geological characteristics and is often the main component of the deep-weathered trough. This article only talk about our superficial understanding of the deep weathered groove.
