地下水的浮力对建筑物设计和施工有不容忽视的影响。结构抗浮验算与地下水的形状、水压力、浮力、地下水位变化的影响因素、意外补水有关,并提出了设计水位计算浮力的概念。地下水位的变化对地基承载力也产生不良影响,因此,必须认真对待,做好地下水的监测和防护工作。 Groundwater buoyancy on the design and construction of buildings can not be ignored. The structure anti-flooding calculation is related to the shape of groundwater, water pressure, buoyancy, influencing factors of groundwater level change and accidental recharge, and the concept of designing buoyancy of water level is proposed. Groundwater level changes also have a negative impact on the bearing capacity of the foundation, therefore, we must take it seriously and do groundwater monitoring and protection.
