根据弹性波浅层地震反射及折射法测试成果，对清江水布垭马崖自然高边坡砂、灰岩岩体按相对低速、波速过渡、波速稳定进行了波速分带以及相应各带岩体的弹性模量Ｅｅｌａ、变形模量Ｅｄｅｆ的指标推算。得到马崖边坡岩体相对低速带一般约４０～６０ｍ，其Ｅｅｌａ范围值８．７～１７．９ＧＰａ，均值１２．５ＧＰａ；Ｅｄｅｆ范围值５．４～１１．８ＧＰａ，均值８．０ＧＰａ。低速带内０～４０ｍ段为卸荷裂隙密集、风化作用明显的区段。深入岩体６０ｍ到过渡或稳定带。６０ｍ后基本为微新岩体范围。依据测试结果对边坡卸荷带岩体质量给予了初步评价，卸荷带内岩体级别一般为Ⅳ以上或Ⅲ以下，未卸荷带岩体一般Ⅱ级或Ⅲ以上，两者相差１～２级。
According to the test result of shallow seismic reflection and refraction method of elastic wave, the wave velocity zonation and the corresponding belt rock mass are carried out according to the relatively low speed, the wave speed transition and the stable wave velocity. Of the elastic modulus Eela, deformation modulus Edef index projections. The relatively low velocity zone of Ma Ya slope is about 40 ~ 60m. The Eela range is 8.7 ~ 17.9GPa, with an average of 12.5GPa. The Edef range is 5.4 ~ 11.8GPa, with an average of 8.0GPa. The low-speed zone 0 ~ 40m section of unloading fissures dense, obvious weathering section. In-depth rock 60m to the transition or stability zone. After 60m basically micro-new rock mass range. Based on the test results, the rock mass quality of unloading belt in slope is preliminarily evaluated. The grade of rock mass in the unloading belt is generally above Ⅳ or below Ⅲ, while the rock mass of unloading belt is generally above Ⅱ or Ⅲ, Level 2
