摘要
将波速测试及高压旁压试验运用于长沙地区的白垩纪红层软岩勘察中,获取了大量红层的声波测试结果及旁压试验特征参数,经过多参数的综合分析,为红层软岩的风化程度与岩体强度变化分析提供了有效参数。并在大量试验资料的基础上,建立了红层的动、静参数之间的相关方程。实践证明,波速-旁压联合测试方法是一种快速、经济、有效的工程勘察手段。
The high pressure pressurement test(PMT) and wave velocity measurement of boreholes are used to get some important information about rock characteristics in cretaceous red layer in Changsha district. Based on the comparison of physical properties between PMT and wave velocity,using the synthetical analysis of multi-parameter,efficient information about rock werthering and strength is achieved. The correlation equations are established for characteristic parameters of dynamic and static properties of soft rock. It is proved that the combined sound wave velocity-pressurement test method is a rapid,economic,and efficient method on in-situ measurement in engineering investigation.
