西安市建筑工程抗浮设防水位研究

Study on Water Level of Anti-floating Construction in Xi’an

西安市对工程建设有影响的地下水为潜水,其水位主要受地貌、含水地层、气象、地表水系、地表水体、城市生态补水及邻近工程降水影响较大,通过对这些影响因素的阐述,结合工程实例,提出不同地貌单元地下水位年变化规律不同,现阶段地下水仍处于整体缓慢上升期,结论可为工程建设者准确、客观地确定建筑场地的抗浮设防水位提供依据。

The groundwater that has influence on the construction of the project in Xi’an is phreatic water,and its water level is mainly affected by the landform,water bearing stratum,meteorology,surface water system,surface water body,urban ecological water supplement and the precipitation of adjacent projects.Combined with engineering examples,the difference of the annual variation of groundwater level in different geomorphic units is put forward.At present,the groundwater is still in the overall slow rising period.The conclusion can provide the basis for anti-floating water level determination in the construction site.
