一、前言在已确定之建筑区进行地下水动态变化的長期观测对于設計建筑物具有重要的意义,因为地下水直接影响地基土的物理力学性質,从而影响到基的稳定性,所以建筑物的基础砌置深度在很大程度上取决于地下水的埋藏深度及其升降变化,在設計地下室及其他地下構筑物时必須以地下水的变化规律作为依据,而进行排水設計时,地下水的埋藏条件又將具有决定性的意义,因此,进行地下水的長期观測,特别是在地下水埋藏較淺的地区,成为工程地質勘測的一項重要任务。
I. INTRODUCTION Long-term observation of the dynamic changes of groundwater in the identified construction areas is of great importance to the design of buildings. Because groundwater directly affects the physical and mechanical properties of foundation so as to affect the stability of the foundation, the foundation of buildings Depth depends largely on the depth of groundwater burial and its movements, in the design of basements and other underground structures must be based on the law of groundwater changes, and drainage design, groundwater burial conditions in turn will have Therefore, conducting long-term observation of groundwater, especially in areas where groundwater is buried shallowly, has become an important task in engineering geological survey.
