Precision Shallow Engineering Seismic Exploration Hardware And Software Systems Research

At environment and engineering perambulate region, not only road bridge foundation survey and tunnel survey and detection, constructional foundation investigation, constructional material or member mass detection, but also landslip calamity survey, reservoir large dam and river dike snag survey as well as the areal geology stability appraise, shallow seismic survey and test method technology are absolutely necessarily and even are the most important instrument at this region, therefor owing to epistratal particularity, such as surface environment intricacy, strata dielectric otherness and stability change as well as the scale of the surveyed object is general on the small side, wherefore, in the field of method technology, it has different from the middle-deep seismic prospecting in data acquisition, processing and interpretation, even has higher require, such as survey precision, SNR and resolution and so on. Seismic data acquisition is one important part of survey, and the factors which impact collection quality mostly have are acquisition methods and the accuracy and reliability of instruments.This paper is under the direction of seismic survey elementary theories, and has detailed analyses and discuss about the developing developmental GDZ-24A type 24-bit A/D High Resolution shallow seismic acquisition system and real-time shallow seismic reflection processing software, and clarify clearly design philosophy and implementation procedure, at integrated design frame, and finished the design of functional modules. Be on the real time gender, mobility, validity and high fidelity ' condition , realized clearly functional module and complete the machine system, simultaneous developed and finished system support software and real-time processing software, after system tests , level of noise, wave distortion and other performances equal to design accuracy require, practical application shows that , complete machine' stability, mobility, validity is high, and can satisfy the demand of shallow layer high precision seismic survey.
