常规反射波法地震勘探中,80 m以内是勘查盲区,为解决这一难题,采用横波浅层地震勘探,在城市浅层地震勘查中,使用200 kg冲击锤的强力横波机械震源激发,小排列、点组合的接收方法,可有效获得80 m以内的有效信息,对城市建筑地基、浅层地质构造及工程勘查等勘探效果明显好于常规地震勘探。
常規反射波法地震勘探中,80 m以內是勘查盲區,為解決這一難題,採用橫波淺層地震勘探,在城市淺層地震勘查中,使用200 kg遲擊錘的彊力橫波機械震源激髮,小排列、點組閤的接收方法,可有效穫得80 m以內的有效信息,對城市建築地基、淺層地質構造及工程勘查等勘探效果明顯好于常規地震勘探。

In the seismic exploration of conventional relfected wave method, the region within 80m is the exploration blind spot. To solve this problem, we use the transverse wave shallow seism exploration. Shallow seismic survey in the urban, with 200kg impact hammer strong transverse mechanical excitation source, receiving method of minispread and point combination can effectively obtain information within 80m. For urban building foundations, shallow geologic structure, engineering survey and other exploration results, this method is better than conventional seismic exploration.
