深基坑工程的支护形式及发展趋势

Support forms and development trend of deep foundation pit engineering

随着城市地下空间的开发利用,基坑工程的面积和深度不断增大,深基坑工程支护的挑战性也越来越大。合理选择支护形式不仅能保证基坑的安全稳定,还能有效的节省成本。依据目前深基坑工程的发展状况,对比分析了不同支护形式的特点和适用条件,并对深基坑支护技术的未来发展趋势做出了思考。

With the development and utilization of urban underground space, the area and depth of foundation pit engineering are increasing, and the support of deep foundation pit engineering is becoming more and more challenging. Reasonable selection of supporting form can not only ensure the safety and stability of foundation pit, but also effectively save costs. Based on the current development of deep foundation pit engineering, the characteristics and application conditions of different support forms are compared and analyzed, and the future development trend of deep foundation pit support technology is considered.
