介绍了尚家河水库右坝肩灌浆前后岩体弹模的变化及利用其变化对灌浆效果进行评估。测试结果表明，在大型水利工程灌浆施工中，利用动弹模的变化来评估灌浆效果具有快速、节省、简便、可靠的优点。
The changes of rock mass elastic modulus before and after grouting in the right abutment of Shangjiahe Reservoir are introduced and the grouting effect is evaluated by using the changes. The test results show that in the large-scale water project grouting construction, the use of dynamic projectile changes to evaluate the effect of grouting is fast, economical, simple and reliable.
