摘要
复合土钉墙是由土钉墙和垂直支护桩所组成,设计时应验算其整体稳定性,而垂直支护桩的桩长直接影响到复合土钉墙的整体稳定性,垂直支护桩存在着临界桩长问题。本文从垂直支护桩对复合土钉墙的整体稳定性的抗滑作用出发,分析了垂直支护桩的桩长对复合土钉墙整体稳定性的影响,并研究了临界桩长的主要影响因素。在工程设计中,应根据临界桩长设计垂直支护桩。
The compound soil-nailing wall was made of the soil-nailing wall and perpendicular protecting piles. The whole stability was checked in the design, while the pile length of perpendicular protecting piles affected directly the whole stability of the compound soil-nailing wall. There was a problem of a critical pile length in the perpendicular protecting piles. Setting out from an anti-sliding function of perpendicular protecting piles on the whole stability of the compound soil-nailing wall, the influence of the perpendicular protecting piles on the whole stability of the compound soil-nailing wall was analyzed, and some main factors of influence for the critical pile length were studied, In the engineering design, the perpendicular protecting piles should be designed according to the critical pile length.
