1 概述小浪底灌溉塔高83m,塔体单薄。它的右侧为3号明流塔,左侧为挡墙,下游侧为山体.周边约束十分复杂。挡墙作为灌溉塔侧向稳定的支撑物,为头南脚北的“T”形结构,坐落在 F28断层及其影响带上。如果地基发生不均匀沉降,灌溉塔与挡墙之间的施工缝就会张开,从而削弱塔体与挡墙的整体性,对塔体的变形、应力和稳定带来不利影响。本文采用无厚度三维等
1 Overview Xiaolangdi irrigation tower height 83m, tower thin. Its right side is No. 3 Mingliu tower, the left side is retaining wall, the downstream side is mountain. The surrounding constraints are very complicated. The retaining wall acts as a laterally stable support for the irrigation tower and is the “T” -shaped structure to the north of the head south, on the F28 fault and its belt of influence. If uneven foundation settlement occurs, construction joints between the irrigation tower and the retaining wall will be opened, weakening the integrity of the tower body and the retaining wall and adversely affecting the deformation, stress and stability of the tower body. This article uses no thickness of three-dimensional
