一、概述 楼房加层具有节约用地,增加房源、造价低、见效快的特点,房屋加层应在建筑物适用、安全、经济前提下,坚持投资省、工期短、见效快、施工简便的原则;但在原有建筑物上加层是一项技术性复杂的工作,它与许多因素有关,如:地基土的种类、基础类型、上部结构体系、作用荷载的性质与大小、房屋使用年限、不均匀沉降的敏感程度等等,而地基承载力计算则是一个关键问题。
I. Overview The addition of buildings has the characteristics of land saving, increased availability, low cost, and quick results. The addition of the house should be consistent with the premise of a suitable building, safety, and economy. It must adhere to the province of investment, with a short construction period, quick results, and easy construction. The principle; but the addition of layers to existing buildings is a technically complex task. It is related to many factors, such as the type of foundation soil, the type of foundation, the structure of the superstructure, the nature and size of the applied load, the age of the house, and not The sensitivity of uniform settlement, etc., and the calculation of foundation bearing capacity is a key issue.
