【摘要】 介绍了三峡升船机及临时船闸高边坡岩体声波测试结果。进一步的分析表明：因控制性因素差异，边坡岩体松弛深度不同。据此可分为表层松弛、浅层松弛和深层松弛，对应的深度期望值分别为０．３～０．５ｍ，２．０～３．０ｍ和５．０ｍ以上更多还原

【Abstract】 The sonic wave measuring results of high rock slope at the boatlift and temporary shiplock of Three Gorges Project are presented. It is shown that the relaxation depth of rock mass at the slope is varied because of the different controlling factors. The relaxation can be classified as surface relaxation, shallow relaxation and deep relaxation. The average depths are 0.30.5m, 2.03.0m and above 5.0m for the three kinds of relaxation.更多还原
