风积沙地层浅层地震勘探及数据处理解译
|
摘要
浅层地震勘探在基岩面和地下构造勘探、地下空洞和不良地质体探测等方面,具有十分显著的应用效果。能为公路、机场、高层建筑等工程选址提供可行性研究和工程规划的基础资料,是一种科学而经济的技术手段。以甘肃某隧道工程预选址工程为例,在深入了解工区地球物理特性的基础上,详细叙述风积沙地层浅层地震勘探数据处理解译方法和枝术。从总体上看,解译成果与钻探成果比对符合程度较高,可以应用于类似地层的工程勘察。
The shallow seismic exploration has been effectively applied to bedrock surface,underground structural exploration,underground cavity and unfavorable geology detection etc.It can provide basic data about feasibility study and project plan for selecting project sites such as highways,airports,tall buildings and others.So this paper takes a tunnel engineering of Gansu pre_site engineering for an example,it detailedly introduces data processing methods and techniques of the shallow seismic exploration in the stratum of aeolian sand on the basis of understanding the geophysical characteristics of the work areas.The results indicate that the results of interpretation and results of drilling have matched well,which can be applied to a similar engineering survey.
