| 摘 要： | 为了解决运营高速铁路线上CPⅡ复测成果异常问题,研究了一种CPⅡ复测成果异常点和异常区段修正方法,此方法中,定义线上CPⅡ异常点和异常区段的限制条件,将本期复测成果与上期复测成果做较差对比,从而发现异常点或异常区段,再采用同精度内插的方式更新异常点或区段,可有效修复线上CPⅡ异常成果,实际修复精度达到毫米级别。最后,结合实际工程数据,验证CPⅡ异常成果修复方法的可行性。

| Abstract: | In order to solve abnormal CPⅡdata of operating rail line,a method to correct abnormal CPⅡpoints and abnormal segments data was made.The method defined limitation factors for abnormal CPⅡpoint and abnormal section and made comparison between retesting results and previous results to find abnormal points or abnormal segments.Interpolation method with same precision level was adopted to effectively repair online CPⅡabnormal results.The accuracy can reach millimeter level.Finally,combined with practical engineering data,the feasibility of the method was verified. |
