摘　　要：地下管线与行道树根系均需占用地下空间,二者间距过小可能导致管线的损坏及其敷设、维修的不便,同时也会影响行道树的正常生长。通过研究二者相互影响情况,归纳分析国内外相关规范的具体要求,对地下市政管线与行道树的安全距离及安全技术措施提出建议。在满足相关规范的前提下,可以通过合理深埋管线、采取防护措施、优选管材和接口形式等方式解决地下市政管线与行道树的相互影响问题。Since underground pipelines and street tree roots both occupy certain underground spaces,inadequate distances between underground pipelines and street trees may lead to pipelines damages and the inconvenience of pipelines construction and repair,meanwhile,the growth of roots might be affected in those procedures.In this paper,interactions between underground pipelines and street trees were studied,and on the basis of technical standards summarization of China and abroad,the safe distances between underground pipelines and street trees as well as the safe technical measures were suggested.It is concluded that on the premise of standards abidance,interaction between underground pipelines and street trees can be minimized through various measures,such as pipeline deep bury,safe technical measures,and optimization of pipeline material and connection.
