ANALYSIS OF THE IMPACT OF TEMPERATURE VARIATIONS ON ROCK BASE PIT SUPPORT PILES
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 tempera-ture field within the rock base pit support piles is uniformly distributed vertically,while it exhibits a linear and mo-notonous 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 optimiz-ing the design of rock deep foundation pit support systems.
