| 摘 要： | 高速公路建设中有大量的通道和涵洞等构造物，高路堤下构造物地基承载力的确定成了设计和施工中必须认真考虑的问题。利用数值方法计算构造物地基的极限荷载，并与太沙基公式或斯凯普顿公式的计算结果进行比较，从理论上分析影响地基承载力的主要因素，同时讨论高路堤下构造物地基承载力的确定。

| Abstract: | There are a large number of constructions such as culverts in highway construction, How to determine the bearing capacity of foundation soil of the constructions under high embankments becomes a problem that must be taken seriously. In this paper, numerical method was used to calculate the ultimate loads of foundation soil, the results of which were compared with those calculated by Terzaghi or Skempton formula. The factors affecting the bearing capacity of foundation soil were analyzed theoretically, and the determinations of the bearing capacity of foundation soil were discussed. |
