摘　　要：利用软土蠕变机理对虎坑大桥的病害现象进行了分析 ,并应用沈珠江基于散体平衡理论导出的公式对软土地基桥台进行了理论分析 ,得出了与实际情况一致的结论 。An analysis was performed on damage to the abutment of Hukeng Bridge, using creep princi-ple of soft clay and formula derived by SHEN Zhujiang based on limited equilibrium theory. Results of the analysis showed an excellent agreement with in situ measurements, providing a theoretical explanation of the cause for the damage.
