近年来,桥梁浅基防护研究工作在各铁路局共同协作下取得了一定的进展。在十二个铁路局共同调查总结我国铁路工务部门桥梁浅基病害防护措施经验的基础上,于1974年1月在南京召开的铁路桥梁浅基防护技术会议上,提出了桥梁浅基九种防护类型及防护原则与适用条件为内容的“运营铁路桥梁浅基防护办法”,及局部防护计算公式。原交通部曾通知各路局供桥梁浅基防护设计施工参考试用。本刊于1974年第5期发表的“桥梁浅基防护调查及试验研究”一文介绍了这一项研究的现场调查总结及局部防护试验研究成果。1975年4月在厦门召开的铁路桥梁浅基整孔防护科技会议上讨论通过了整孔防护计算公式,铁道部工电局于今年1月汇集局部防护及整孔防护计算公式发函通知各路局参照试用。现摘要介绍整孔防护试验研究结果,供读者参考。
In recent years, the research on shallow foundation protection of bridges has made some progress under the joint cooperation of all railway administrations. Based on the investigation and summary of the experience of shallow foundation disease prevention measures of bridges in China’s railway construction sector, the 12 railway administrations jointly proposed the shallow foundation nine protection measures for bridges and bridges at the shallow bridge protection technology conference held in Nanjing in January 1974, Type and protection principles and applicable conditions for the content of the “operation of shallow protection of railway bridges,” and local protection formula. The former Ministry of Transportation had informed all railway bureaus for the shallow foundation of the bridge design and construction of reference test. The publication published in the fifth issue of 1974, “Bridge shallow base protection investigation and experimental study,” a paper describes the field investigation concluded that this study and local protection test research results. April 1975 held in Xiamen Railway Shallow Shield Protection Science and Technology Conference discussed and adopted the calculation formula for protection of the entire hole, the Ministry of Railways Bureau of Electrical and Mechanical Services Bureau in January this year, the Department of protection and the entire hole protection calculated formula letter sent a letter to inform Bureau reference trial. Now summarize the whole hole protection test results for readers reference.
