抗拔锚杆作为一项竖向锚固技术,在施工工期与工程成本上显示其优越性,但本文工程中,地下工程规模大,地下水位较高,无现行案例可循。以场区岩土情况为出发点,从降低工程造价角度,在满足标准前提下,对抗拔锚杆进行了合理优化和改进。实践证明,锚杆质量和抗拔力均可满足要求。
抗拔錨桿作為一項豎嚮錨固技術,在施工工期與工程成本上顯示其優越性,但本文工程中,地下工程規模大,地下水位較高,無現行案例可循。以場區巖土情況為齣髮點,從降低工程造價角度,在滿足標準前提下,對抗拔錨桿進行瞭閤理優化和改進。實踐證明,錨桿質量和抗拔力均可滿足要求。

The anti?pull anchors as a vertical anchoring technique show its superiority in the construction period and the cost of the project. With the large scale of the underground engineering and high level of underground water, current case can’ t be followed. Based on geotechnical conditions of the area as a starting point, the perspective of reducing project cost and meeting the standards, the anti?pull anchors are optimized and improved reasonably. Practices show that the quality and anti?pull load can meet the requirements.
