摘要
文章结合工程实例,基于有限元数值模拟软件对基坑分步开挖过程中的水平位移进行数值模拟。结果表明:基坑围护桩、坑外土体以及坑底土体所产生的水平位移值随着锚索的施加,均得到了有效的控制,在规范所建议的范围内。水平位移值随开挖步的进行逐渐增大,第九步均达到最大值,水平位移的最大值发生在围护桩。
Combined with engineering examples,the paper analysed the horizontal displacement through the numerical simulation during the stepwise excavation based on the finite element numerical simulation software.The results showed that:with the applied of anchor, the horizontal displacement, which in the supporting pile of foundation pit, soil outside and at the bottom of the pit is controlled effectively, and in the specification of the recommended range.The value of horizontal displacement has increased with the excavation, and reached the maximum in the ninth step, the maximum horizontal displacement has occured in supporting pile.
