深基坑支护不仅要求确保边坡的稳定,而且要满足变形控制要求,以确保基坑周围的建筑物、地下管线、道路等的安全。如今支护结构日臻完善,出现了许多新的支护结构形式与稳定边坡的方法。深基坑支护设计与施工是当前城市高层、超高层建筑突显的技术难题。复合土钉在深基坑支护,能减少边坡开挖,缩短施工工期,减少基础工程投资。因此,在这里对深基坑支护的施工工艺及其设计原理进行了简要的研究,以供同行参考。
The deep foundation pit support not only requires the stability of the slope, but also meets the deformation control requirements to ensure the safety of buildings, underground pipelines, and roads around the pit. Nowadays, the supporting structure is improving day by day, and many new forms of supporting structures and methods for stabilizing slopes have emerged. The design and construction of deep foundation pit support are the technical problems highlighted by the current high-rise and high-rise buildings in cities. Composite soil nails are supported in deep foundation pits to reduce slope excavation, shorten construction period, and reduce investment in basic projects. Therefore, here a brief study on the construction process and design principles of deep foundation pit support is provided for reference by peers.
