摘　　要：针对当前地铁勘察工程对旁压试验的要求,介绍旁压试验的测试校正和数据处理方法,结合具体工程实例的旁压试验原位测试,由旁压曲线得到不同土壤的静止侧压力、临塑压力和极限压力,继而提出旁压模量、旁压剪切模量等变形参数的处理方法。For the survey requirements of the subway project in situ testing,this paper introduces the pressure meter test calibration and data processing method.Combined with specific examples of projects situ pressure meter test,static lateral pressure,critical plastic pressure and limit pressure is obtained through the analysis of the P-V curve in the different soil horizon.Subsequently the method of data processing is put forward for pressure meter modulus and shear modulus and other deformation parameters.
