摘　　要：浅层地震折射波法勘探受地形起伏影响小,资料解释比较容易,能够提供基岩覆盖层厚度及覆盖层、基岩的纵波波速,而广泛应用于工程地质勘察。候家梁隧道工程测区部分地形起伏较大,工区基岩上覆地层有相对低的速度,应用地震折射波法勘查,得出的资料解释与实际情况相符,可信度高,为工程建设提供了有效的地质依据。Shallow seismic refraction prospecting is affected less by topography and the data are easily interpreted, which can provide the overburden thickness, covering layer and lon- gitudinal wave velocity of the bedrock, so it is widely applied to the engineering geological survey. Some surveying areas in Houjialiang tunnel are involved in topographic influence and compared to high velocity in bedrock, the covering layer has a lower velocity. The shallow seismic refraction prospecting method is used to get data interpretation that is con- sistent with the actual situation. Due to its high credibility, it provides an effective geolog- ical basis for the engineering construction.
