Effects of dewatering methods on seepage and deformation of foundation pits

  • 摘要: 人工降低基坑水位是基坑工程中的常用技术手段之一,需要合理评价其在地基中引起渗流及附加的变形。采用Visual MODFLOW数值计算软件分析降水条件下武汉某基坑工程的渗流场,并采用分层总和法计算地基变形场。结果表明,随着离基坑的距离增加,基坑外的水头逐渐增大,而地基沉降逐渐减小。增加帷幕深度可以提高降水效果,并有效减小基坑降水引起的沉降。
    Abstract: A usual approach for foundation pits is to decrease water level. It is necessary to evaluate the seepage and induced deformation in the soil base. The numerical simulation software, Visual MODFLOW, is used to analyze the seepage field of a foundation pit in Wuhan. The deformation of the soil base is accordingly derived using the layer-wise summation method. The analysis results show that the water level increases and the settlement of the soil base decreases as the distance from the foundation pit increases. The water level exhibits a significant loss near the curtain. The settlement decreases rapidly near the curtain, and the decrease rate becomes small when the distance is fairly large. The dewatering effect will increase and the settlement of the soil base decreases if the curtain depth increases.
