摘要:
依托东北某土石坝工程,提出一种“钢板桩+型钢”复合加固体系。基于朗肯土压力理论和Winkler弹性地基梁模型,计算分析三种型钢组合(槽钢、工字钢、钢管桩)的内力与变形响应,并探究桩顶锚拉力的影响。结果表明:3种方案均能有效控制地基变形,其中钢管桩组合侧向位移最小;桩身最大弯矩与位移集中于深部流塑状淤泥质黏土层;施加50 kN/m桩顶锚拉力仅改善桩头局部变形,对桩身中下部关键受力与变形影响微弱。研究结论可为类似深厚软土坝基抗滑桩设计提供参考。
Abstract:
Relying on an earth-rock dam project in Northeastern China, a “steel sheet pile + section steel” composite reinforcement system is proposed. Based on Rankine’s earth pressure theory and the Winkler elastic foundation beam model, the internal force and deformation responses of three section steel combinations (channel steel, I-beam, steel pipe pile) are calculated and analyzed, and the influence of pile top anchor tensile force is investigated. The results show that all three schemes can effectively control foundation deformation, among which the steel pipe pile combination has the smallest lateral displacement. The maximum bending moment and displacement of the pile are concentrated in the deep flow-plastic silty clay layer. Applying a 50 kN/m pile top anchor tensile force only improves the local deformation at the pile head, and has negligible influence on the critical stress and deformation in the middle and lower parts of the pile. The conclusions can provide a reference for the design of anti-slide piles in similar deep soft soil dam foundations.
