Regression analysis of influence law of urban pavement settlement caused by underpass tunnel construction in Beijing
-
摘要: 以朝阳区某热力工程顶管隧道引起路面沉降问题为例，对比分析了现场实测值与仅考虑自然因素的理论计算值；以北京市279个隧道下穿道路工程为样本，应用Stata 14.0统计软件对影响路面沉降的4项设计因素、3项施工因素和9项人为因素开展了多元回归分析，并采用替换施工方法、增减解释变量的方法验证了回归分析的稳健性，获得了各因素影响路面沉降的弹性系数、标准误及置信等级。研究结果表明：实际工程路面沉降的实测值与理论计算值相差很大，与路面是否有移动荷载、隧道上覆土体厚度等相关，最大可达3.75倍；在自然因素中，地层条件、施工方法、路面移动荷载和隧道直径的影响显著，影响程度依次降低；在人为因素中，监理旁站的影响极为显著，而施工人员工作年限、是否有技术交底等也有明显影响；在采用非开挖技术施工下穿道路工程时，不仅要通过减少人工顶管、加快施工速度、加强同步注浆来减小路面沉降，还应当高度重视施工方法与工艺、人员组织、过程监管。研究结果可为隧道下穿城市道路施工的技术管理、安全评估和行政审批提供参考。Abstract: Taking the pavement settlement caused by pipe jacking tunnels in thermal engineering in Chaoyang District of Beijing as an example, the on-site measurement value and the theoretical computation values that only considering natural factors were compared and analyzed. With 279 tunnel underpass projects in Beijing as samples, the multiple regression analysis was carried out with the statistical software Stata 14.0, where four design factors, three construction factors, and nine human factors affecting the pavement settlement were involved. Then, the robustness of regression analysis was verified by the replacement of the construction methods and the addition or subtraction of interpretation variables, and the elasticity coefficients, standard errors, and the confidence levels of each factor affecting pavement settlement were obtained. Analysis results show that a huge difference exists between the on-site measurement and the theoretical computation in the pavement settlement, which is related to the existence of moving loads on the pavement and the thickness of the overlying soil of tunnels, with a maximum of up to 3.75 times. Of the natural factors, the influence of geological condition, construction method, moving load on the pavement, and tunnel diameters are significant, and the degree of influence decreases in turn. Of the human factors, on-site supervision plays a significant role, and working years of constructors and technical disclosure also have a great impact. In the construction of an underpass project with a non-excavation method, we should reduce the manual pipe jacking, accelerate construction, and consolidate synchronous grouting to decrease the pavement settlement, and great significance should be attached to the construction technology and process, personnel organization, and process supervision. The research results can provide a reference for the technical management, safety assessment, and administrative approval of the construction of tunnels undercrossing urban roads. 6 tabs, 4 figs, 30 refs.
