基于时空分布模型的混凝土面板堆石坝挤压边墙变形监测资料分析

基于挤压边墙多测点变形监测资料,通过引入监测点的空间坐标标量,结合场理论建立了挤压边墙变形时空分布模型。结合建设中的涔天河水库扩建工程挤压边墙的实测变形资料,验证了本文建立的挤压边墙变形时空分布模型。结果表明,该混凝土面板堆石坝挤压边墙的监测区域上部仍处于发展状态,尚不适合面板混凝土的施工。

Temporal-spatial distribution model-based analysis on deformation monitoring data of extruded sidewall for concrete face rock-fill dam

Based on the multipoint deformation monitoring data of the extruded sidewall，a temporal-spatial distribution model for the deformation of the extruded sidewall is established in combination with the field theory through introducing in the scalars of spatial coordinates for the monitoring points. Combined with the measured deformation data of the extruded side wall from the under-construction Centianhe Reservoir Expansion Project，the temporal-spatial distribution model for the deformation of the extruded sidewall established herein is verified. The relevant analysis shows that the upper part of the monitored area of the extruded sidewall for the concrete face rockfill dam is in a status of development，thus is unsuitable for the concrete construction for the face slab yet.
