西安地裂缝二类场地勘察标志层识别及勘探孔深度确定
摘要:西安地裂缝是一种地区性的地质灾害现象。目前,已发现的西安地裂缝有14条,对西安的工程建设带来不同程度的危害。在西安地裂缝二类场地勘察过程中,通常是将上更新统和中更新统红褐色古土壤作为勘探标志层。根据西安地形地貌及地层沉积特征,将西安地裂缝二类勘察场地划为3个亚区,提出在不同亚区采用相对应的判断地裂缝出露标志层以及勘探深度,对西安地裂缝二类场地的勘察方案布置及过程实施具有指导意义。
Abstract:Xi'an ground fissure is a kind of regional geological disaster.At present,14 ground fissures have been found in Xi'an,which bring different degrees of harm to Xi'an's engineering construction.Usually,the Upper Pleistocene and Middle Pleistocene reddish brown palaeosol are used as exploration marks during investigation in the second class of Xi'an ground fissures site.According to the characteristics of Xi'an topography and stratigraphy,the second class of Xi'an fissures site can be classified into 3 sub regions.It is suggested that we should use the corresponding judgement of the outburst signs and exploration depth in different sub regions.It has guiding significance for the layout and process implementation of second class of Xi'an ground fissure sites.
