Design and construction method for foundation pit above axial force servo control tunnel upheaval
The invention discloses a design and construction method for an upper foundation pit with axial force servo control over tunnel upheaval. The design and construction method for the upper foundation pit with the axial force servo control over the tunnel upheaval is small in pit bottom reinforcing amount, convenient to construct and capable of effectively controlling the upheaval deformation problem of an existing tunnel. The method sequentially comprises the following steps that 1, a construction area is divided, specifically, a foundation pit is divided into a first construction block and a second construction block, and the first construction block is located over a tunnel and extends in the length direction of the tunnel; a foundation pit enclosure and supporting stand column piles are constructed, the foundation pit enclosure comprises a foundation pit enclosure wall and a horizontal supporting beam, and the supporting stand column piles support the horizontal supporting beam; secondly, foundation pit construction of the first construction block is conducted; the method comprises the following specific steps that a first construction block is divided into a plurality of excavation blocks in the length direction of a tunnel; and each excavation block is excavated. And 3, foundation pit construction of the post-construction block.
本发明公开了一种轴力伺服控制隧道隆起的上方基坑设计施工方法，旨在提供一种坑底加固量少、施工方便，能够有效控制既有隧道的隆起变形问题的轴力伺服控制隧道隆起的上方基坑设计施工方法。它依次包括以下步骤：一，划分施工区域，将基坑划分为先施工区块与后施工区块，其中先施工区块位于隧道的正上方并沿隧道长度方向延伸；施工基坑围护和支撑立柱桩，基坑围护包括基坑围护墙及水平支撑梁，支撑立柱桩支撑水平支撑梁；二，先施工区块基坑施工；具体步骤如下，将先施工区块沿隧道长度方向划分为若干个开挖区块；对各开挖区块进行开挖。三，后施工区块基坑施工。
