| 摘 要： | 通过对内蒙古自治区老集高速公路测量控制点高程发生变化,以至线路复测时,高程闭合差超限的分析,阐述了除正常测量本身所产生的误差外,高程控制点的变化还受气候、地形、土壤、含水等综合因素的影响,同时指出,造成高程变化的根本原因是高程控制桩在冻融过程中产生了冻拔和融沉作用,并具有一定的规律性。 |

| Abstract: | The elevation of control points for survey in Laoyemiao-Jining Expressway in Inner Mongolia had a change,which results in the closing error of elevation was out of limit when the complementary survey of routine was carried out.In addition to the normal error of survey,the actual causes were influenced by the climate,the topography,the soil,the water content,etc.The main factors are the frozen-heave and thaw collapse action to the control pile in the process of freezing and thawing,which have some regularity. |
| Keywords: | elevation variation frozen thaw collapse analysis |
