紫坪铺水利枢纽固结灌浆效果的显著性分析

摘要

通过运用声波、弹模检测等综合物探方法，分别在紫坪铺水利枢纽泄洪排砂洞固结灌浆前后进行对比检测，并对检测结果采用假设检验的方法进行分析，从而对灌浆效果的显著性做出合理的评价。%By adopting the comprehensive geophysical methods, such as the sound wave and the elasticity moduli test, the paper undertakes the comparative tests on the flood discharging draining sand tunnel of Zipingpu hydro-junction before and after the consolidation grouting, and analyzes the test results by adopting the hypothesis testing, so as to achieve the reasonable evaluation for the significance of the grouting effect.
