基础埋置深度的确定需满足地基稳定和变形要求,上层地基承载力大于下层土时,宜利用上层土作持力层。基础埋深一般不应小于0.5m。高层建筑基础埋深需满足地基承载力、变形和稳定性要求。岩石地基上高层建筑基础埋深需满足抗滑稳定性要求。抗震设防区,天然地基上箱形、筏形基础埋深不宜小于建筑物高度的1/15,桩箱或桩筏基础埋深不宜小于建筑物高度的1/18。基础应尽量埋置在地下水位以上,必要时应采取防扰动措施。在易风化岩层上施工,应在开挖后立即铺筑垫层。相邻建筑物时,新建建筑基础埋深不宜大于原有基础,两基础间保持一定净距,依据建筑荷载、基础形式和土质情况确定。超过50米的钢结构房屋应设置地下室,采用天然地基时埋深不宜小于总高度的1/15,采用桩基时桩承台埋深不宜小于总高度的1/20。
