摘要: 根据建筑物下部采煤巷道的断面尺寸、位置及埋深等地质条件,针对地面拟建建筑物的特点,分别应用二维及三维离散单元方法,对工程场地的地面变形进行了定量评价,得出了地面建筑物在巷道影响下的水平位移量及竖向位移量。结果分析认为,地下巷道的存在不会对上部建筑物造成威胁,仅会产生微小沉降变形。同时提出了一些工程安全措施,为工程建设的顺利实施提供了必要依据。

Abstract: Based on the geological conditions,such as the cross dimension,the position and the embedded depth of the coal tunnel,and according to the characteristics of quasi-ground building,the ground deformation of engineering site is quantitatively evaluated by applying the two-dimensional and three-dimensional Distinct Element Method.The horizontal displacement amount and vertical displacement amount of ground buildings generated by coal tunnel are got.It can be seen from the results that the existence of underground tunnel cannot bring dangers to upper buildings,but only create minute settlement deformations.At the same time,some engineering safety measures are put forward to supply necessary rules for favoring execution of engineering constructions.
