抗浮锚杆在U型槽中的应用

Application of Anti-float Anchor Bolt in U-type Trough

宁远道口下穿立交设计中,地下水位高,道路U型槽设计中,岩层较浅的条件下,利用抗浮锚杆起到抵抗地下水浮力的作用,通过理论计算和现场试验来确定锚杆的入岩深度,已达到经济、便捷、安全的效果。

In the design of Ningyuan Intersection Underpass,the underwater level is high.The anti-float anchor bolt is used to resist the floating force of underwater in the design of U-type trough of road under the condition of more shallow rock stratum.The depth of anchor bolt in rock is defined by the theoretical calculation and the field test,which has achieved the economic,convenient and safe effect.
