摘　　要：为了能更充分地发挥勘探孔的作用,有效查明城市道路地质条件,尤其是最大限度避免出现漏查暗塘暗浜现象,以达到减少设计变更目的,对现行《市政工程勘察规范》（CJJ56-2012）中对城市道路一般路基的勘探孔平面布置规定进行了讨论,采用类比方法,结合实际工程案例分析,提出坚持中线布孔结合边线布孔优化思路,并提供三种具体布孔方案,比较优缺点,供岩土工程师择优采用。In order to make better use of the exploratory holes and effectively ascertain the geological conditions of urban road,especially to avoid the presence of missed hidden creeks,ultimately achieving the goal of reducing construction design alteration,this paper made a detailed discussion on the arrangement about exploratory holes layout in the code for geotechnical investigation of municipal engineering projects（ CJJ56-2012）,making use of the method of analogy,combining analysis with practical engineering cases,and finally put forward the idea that we should insist on the optimization of exploratory holes layout in the road centerline in combination with the road side at the same time. At last,the paper proposed three exploratory holes layout schemes,comparing the advantages and disadvantages between which,in order to be chosen by the geotechnical engineers.
