摘要
带锚双排桩是在双排桩的基础上结合锚杆支护,可以达到提高桩体整体稳定性、有效缩短工期、提高经济效益的目的。文中分析了双排桩的土压力与内力计算方法,结合工程实例,研究了带锚双排桩在深基坑支护中的应用,并对带锚双排桩的弯矩、剪力和位移的计算方法进行分析。分析表明:锚索的受力作用显著,使得各监测点位移较小;带锚双排桩的累计变形量均在控制范围内。现场数据的对比分析验证了计算模型的准确性和适用性。
Anchored double-row piles integrate the double-row pile system with anchor rod support,aiming to improve the overall stability of the pile body,effectively shorten construction periods,and enhance economic efficiency.Combined with engineering cases,investigates the application of anchored double-row piles in deep foundation pit support engineering by summarizing the calculation methods for soil pressure and internal forces in double-row piles.The bending moments,shear forces,and displacements of anchored double-row piles are analyzed.Field results show that the displacement at each monitoring point is minimal due to the force applied by the anchor cables,and the cumulative deformation remains within the controlled range.These results validate the accuracy and applicability of the calculation model.
