摘要
通过对喷锚支护与土钉墙受力及作用机理的分析 ,揭示了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 ,其受力更合理 ,因此 ,在条件允许情况下 ,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 shot-anchoring protection,it has the features of low cost of construction and convenience in construction.Compared with the rigid protection,the deformation and effect on dependent-time for the flexible protection makes it more reasonable for the stress.Therefore,to use them,such as soil-nailing wall est.,may greatly reduce the investment if the condition permits.
