摘　　要：通过对长沙市某工程复杂场地条件下长距离非开挖导向钻进技术的应用研究,提出在类似场地条件下施工应尽量全面收集施工场地已有管线及地下构筑物资料;根据场地条件合理设计导向孔轨迹;配制钻进泥浆并合理选择泥浆添加剂;选择适合长距离拖管的拖管组件。After researched on long distance trechless pilot drilling in certain project under complicated space conditions in Changsha, the author suggested that the information about underground pipe lines and other structures should be collected as completely as possible while engineering under similar conditions, that the pilot borehole trajectory should be reasonably designed based on space conditions, that drilling mud should be prepared and mud additives should be reasonablely selected and that pipe drawing assembly should be suited to long distance pipe drawing.
