喷锚支护与土钉墙

Shot-anchoring Protection and Soil-nailing Wall

通过对喷锚支护与上钉墙受力及作用机理的分析，揭示了由于土钉墙能充分利用土体的自承能力的特点，与喷锚支护相比，造价低，施工方便；与“刚”性支护相比，柔性支护的变位与时效作用，其受力更合理。因此，条件允许的情况下，采用“土钉墙”等柔性支护，可以大大节省投资。

Based on the mechanism for shot - anchoring protection and soil - nailing wall, the characteristics which the self- bearing capacity of soil -nailing wall is taken full advantage of is expounded. Compared with the shot-anchoring protection,it has the features of low cost of construction and convenience to construction. Compared with the rigid protection,the deformation and effect on dependent -time for the flexible protection make it more reasonable for the stress. Therefore,to use them,such as soil-nailing wall etc,may greatly reduce the investment if the condition allowed.
