三峡船闸高陡开挖边坡主要监测资料分析

通过对三峡船闸边坡形成后变形观测成果的系统分析,说明了边坡不同部位变形的收敛特点.分析表明,中隔墩和南、北直立坡顶的变形收敛很快,其上部大部分斜坡表面测点变形也在收敛,坡顶个别部位全强风化岩体上的测点收敛速度相对较慢,但对边坡稳定没有影响.

Analysis of main monitoring data of high-steep slope of Three Gorges Shiplock

The convergent characteristics at different monotoring points of the high-steep slope of Three Gorges Shiplock are explained on the basis of systematically analyzing the deformation at that place. At the imermediate rock wall and the top of bothsides vertical wall, the deformations converge quickly; at great part of upper slope surface, the deformations converge as well; at very few points near the top of high-steep slope, the deformations converge relatively slow, but no influence on stability of high-steep slope.
