桥梁施工,尤其是通航桥梁施工容易发生事故。通过对高速公路建设中造成安全事故的原因调查分析,根据现场统计资料回归数学模型,制定桥梁施工安全的控制措施,从项目负责人到普通员工都要参与进去,把安全生产放在重要的地位,做到安全生产人人有责,对保障工程质量和工程进度都是非常有益的。安全事故发生的主要原因基坑开挖施工过程中,人工开挖基坑,护壁处理不及时,造成基坑坍塌;清孔排水时,未注意保持孔内水头造成内外压
Bridge construction, especially the construction of navigation bridge prone to accidents. Through the investigation and analysis of the causes of accidents caused by the expressway construction, according to the regression mathematical model of the on-site statistics, the control measures for the construction safety of the bridge are formulated. From the project manager to the general staff, both should be involved in putting safety production in an important position , Everyone responsible for safe production, to protect the quality of the project and the progress of the project are very useful. The main cause of accidents The excavation of the excavation process, artificial excavation pit, wall treatment is not timely, resulting in pit collapse; clearance hole drainage, did not pay attention to keep the hole head caused by internal and external pressure
