| 摘 要： | 双塘崖墓群为古人在砂岩岩壁开挖的石洞，其空间分布及规律性差，铁路以路基方式通过。崖墓极易造成路基不均匀沉降，而无砟轨道对沉降控制要求极高。采用何种勘察方法，查清崖墓的分布、评价其对工程的影响极为重要。结合现场调绘，以工程物探为指导，采用地质钻探、钎探等多种手段，查明了其空间分布，再通过技术处理，确保了工程安全。

| Abstract: | Shuangtang cliff tomb group is rock cavity excavated by the ancients in the sandstone crag, in respect of which the spacial distribution and the regularity is poor; thus railway passes through it by means of subgrade. control of However, cliff tomb is easy settlement strictly, so which to make uneven settlement of subgrad survey method is used is importante, and ballastless track requires for investigation of cliff tomb＇s distribution and evaluation of its effect on the engineering. Combined with field annotation and guided by engineering geophysical exploration, this paper applied geological exploration by drilling or drill rod and other methods to investigate the spacial distribution of the cliff tomb group. Through technical treatment,engineering safety was ensured. |
