上海长江隧道抗浮模型试验与理论研究

饱和软土盾构隧道施工中,对于刚脱出盾尾的隧道经常会出现局部或整体上浮,隧道直径越大、覆土越浅,上浮现象越为突出,表现为隧道错台大、螺栓被剪断乃至轴线偏位,影响到隧道的稳定和施工质量等,传统抗浮设计未能考虑处于时变特性单液浆中隧道的浮力动态因素,现行相关设计规范也没有对隧道抗浮设计和施工措施做出明确的规定。文章首先介绍了上海长江隧道抗浮模型试验与结果,确定了超大直径隧道动态上浮力,以此为基础提出了隧道上浮稳定机理,并建立了盾构隧道上浮计算的理论模型,据此进行了上海长江隧道抗浮验算,并提出了相应的抗浮技术措施。     

高压旋喷工艺中喷射流切割效果影响因素的研究

高压旋喷工艺中高压喷射流对土体介质的切割破坏是其核心技术,但以往对该问题的认识与研究仍然停留在定性阶段.借助物理模拟试验和数值模拟两种手段,对影响高压喷射流的切割效果有关因素进行了定量研究,得出了有益的结论,研究思路与成果可为同类问题提供借鉴与参考.
