超深圆形基坑承压水减压技术及对环境的影响

Compression Water Pressure-Reduction Technique for Super Deep Circle-Foundation Pit Environment and Its Effect on Environment

以上海浦钢公司搬迁工程——轧钢区旋流池基坑为例,介绍了在软土地质条件、承压地下水、周边环境复杂等地质条件下,超深圆型基坑采取了承压水减压手段,并对承压水和周边环境进行信息化监测,保证了基坑的开挖封底和周围环境的安全。

Taking the foundation pit engineering for spiral flow tank of hot rolled steel area of Shanghai Pudong Steel Company as example, the paper introduces the application of compression water pressure-reduction technique for super deep circle foundation pit under the condition of soft soil, compression underground water and complex surrounding geology. Informationized monitor to compression water and surrounding environment was made so as to ensure the cxcavation and safe bottom closing of foundation pit.
