【摘要】 为探究气温年变化对岩石基坑支护桩温度场及应变场的影响规律，文中采用数值模拟的方法分析了气温年变化引起的支护桩温度应变场的分布规律。研究结果表明，岩石基坑支护桩内的温度场沿竖向呈均匀分布，而沿桩径方向则呈线性单调分布；支护桩基坑侧和迎土侧表面竖向温度应变呈现正弦变化的规律。研究为岩石深基坑支护体系的优化设计提供参考依据。更多还原

【Abstract】 To investigate the impact of annual temperature variations on the temperature and strain fields of rock base pit support piles, a numerical simulation method was used to analyze the distribution patterns of temperature and strain fields in support piles caused by annual temperature changes. The study results indicate that the temperature field within the rock base pit support piles is uniformly distributed vertically, while it exhibits a linear and monotonous distribution along the pile radius direction. The vertical temperature strain on the support pile’s pit side and soil-facing side follows a sinusoidal variation pattern. This research can provide valuable references for optimizing the design of rock deep foundation pit support systems.更多还原
