| 中文摘要:观测基坑及其周围建筑物在基坑施工阶段的沉降，对保证施工安全具有重要意义。基坑施工沉降观测一般采用固定基准，因此要求有稳定的水准基点，工作基点稳定与否也直接关系到联测和有关沉降计算。研究了水准基点和工作基点稳定性的分析方法，结合基坑施工沉降观测实际，利用基准网观测数据进行水准基点稳定性分析，利用水准基点与工作基点的联测数据进行工作基点稳定性分析，保证了基坑及其周围建筑物沉降的真实性。 |

| Abstract:It is important to ensure construction safety to monitor settlement of foundation pit and the round buildings. The fixed height datum are usually selected in settlement observation, the stable basic benchmark is needed consequently, the stability of the operating control point play an important part in connection survey and settlement calculation. The analysis method of basic benchmark and operating control point are researched. Based on the settlement observation in foundation pit construction, the stability of basic benchmark and operating control point are analyzed by the survey data of datum network and the connection survey data of basic benchmark and operating control point, the accuracy of settlement data of foundation pit and the round building are ensured. |
