毕业设计（论文） 题 目：面波在地震波场中的特性研究及其应用 Surface wave in the characteristics of seismic wave field research and its application 学生姓名：高振兵 专 业：勘查技术与工程 班 级指导教师：方根显 二零一一年六 月 摘 要 瑞利面波勘探是近年 HYPERLINK /fazhan/ 发展起来的一种新的浅层地球物理勘探方法，具有简便、快速、 HYPERLINK /Economic/ 经济、分辨率高、成果直观、适用场地小等优点，已在许多领域得到应用，并取得了良好的应用效果[1]。瑞利面波是一类频率较低、能量较强的次生波，且主要沿着介质的分界面传播，其能量随着与界面距离的增加迅速衰减。瑞利面波与反射波、折射波一样都含有地下介质的地质信息。本文从瑞利面波的概念、工作原理及方法、频散特征、反演研究以及实际资料的应用等方面，用多道检波器测量来了解面波勘探在浅层地表调查中的应用。 关键词: 瑞利面波、频散曲线、波动方程、瞬态瑞雷波勘探。 ABSTRACT Rayleigh wave exploration is developed in recent years, a new shallow geophysical exploration methods, it is a simple, quick, economy, high resolution, achievements intuitive, applicable site, has the advantages of small find application in many fields, and have achieved good application effect. Rayleighs is a kind of lower frequency, energy strong secondary wave, and mainly the boundary surface along the medium, the energy with the spread of interface distance attenuation increases rapidly. Rayleigh wave reflection wave, with all contain the same refraction wave of underground medium geological information. This article from Rayleighs concept, principle and method , frequency dispersion characteristics, and inversion study and the actual material application etc, with multi-channel detectors measurements to understand surface wave exploration in the application of shallow surface survey. keywords: Rayleigh wave，frequency disperse curve, wave equation, transient state Rayleigh wave prospecting. 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc294428760 绪 论 PAGEREF _Toc294428760 \h 1 1.工区自然地理和地质、地球物理特征 3 HYPERLINK \l _Toc294428761 1.1工区自然地理 PAGEREF _Toc294428761 \h 3 HYPERLINK \l _Toc294428762 1.2工区地质概况 PAGEREF _Toc294428762 \h 4 HYPERLINK \l _Toc294428763 2.工作方法与技术 PAGEREF _Toc294428763 \h 4 HYPERLINK \l _Toc294428764 2.1 面波勘探的基本原理及特点 PAGEREF _Toc294428764 \h 5 HYPERLINK \l _Toc294428765 2.2 野外工作方法 PAGEREF _Toc294428765 \h 7 HYPERLINK \
