岩体风化岩体风化rockmass，weatheringof在水、大气、温度和生物等营力的作用下，地壳上部岩体的物质成分和结构发生变化，从而改变岩体力学性质的过程和现象。风化了的岩体工程地质性能发生恶化，给建筑工程带来不良影响。一般情况下，岩体的风化程度呈现出由表及里逐渐减弱的规律。但由于岩体中岩性并不均一，且有断裂存在，所以岩体风化的情况并不一定完全符合一般规律。岩体风化厚度一般为数米至数十米，沿断裂破碎带和易风化岩层，可形成风化较剧的岩层。断层交会处还可形成风化囊。在这两种情况下深度可超过百米。根据风化程度，一般将岩体的风化部分划分为3个或4个风化带。分带多少视建筑物类型、规模，以及各部门的习惯而有所不同。划分风化带的方法大致有3种：①现场根据岩石颜色、矿物晶面光泽和粗矿物颗粒的变化、裂隙发育程度、锤击反应和手控易碎程度用肉眼鉴定。②用化学或矿物成分分析方法鉴定活动金属元素的迁移程度或易风化矿物的变异比率。③用简易的物理力学性质测试方法测试风化岩石与新鲜岩石单轴抗压强度的对比、回弹状况和点荷载变化。划分风化带的目的在于建筑施工时，充分利用可利用的部分，挖除不能满足施工要求的部分以确保工程安全，并减少施工量和工程费用。
