高速公路拓宽工程复合地基处理效果的数值分析
Numerical analysis of improvement effect with composite foundation method for expressway widening engineering
以在建高速公路地质资料为背景，通过通用的有限元程序，对高速公路拓宽工程中新路基采用复合地基处理方法的效果进行了数值模拟。结果表明：隔离墙能有效地减小路基的水平位移，新路基采用复合地基法处理能较好地解决不均匀沉降问题。
Based on the geologic data of a constructing expressway，for its widening engineering，the improvement effect of new and old road foundations with composite foundation method is simulated numerically by popular FEM program. Result shows that separating wall can be effectively used to reduce the horizontal displacement of embankment; and the new road foundation with composite foundation method will produce less differential settlement.
