量测方法

(一)地质素描

与隧道施工进展同步进行的洞内围岩地质(和支护状况)的观

察及描述,通常称为地质素描。是隧道设计和施工过程中不可缺少的

的地质勘查工作,是对围岩工程地质特性和支护措施和理性的最直

观、最简单、最经济的描述和评价。一般包括对以下内容的描述:

①代表性测试断面的位置、形状、尺寸及编号;

②岩石名称、结构、颜色;

③层理、片理、解理裂隙、断层等各种软弱面的产状、宽度、延

伸情况、连续性、间距等;个结构面的成因类型、力学属性、

粗燥程度、充填的物质成分和泥化、软化情况;

④岩脉穿插情况及其与围岩接触关系,软硬程度、破碎程度。

⑤岩体风化程度、特点、抗风化能力;

⑥地下水的类型、出露位置、水量大小及喷锚支护施工的影响等;

⑦施工开挖方式方法、喷锚支护参数及循环时间;

⑧围岩内鼓、弯折
