摘要

如果深层地基在经济上不是可行的解决方案,地基较差的低层住宅发展项目可能会出现地基问题。对于轻荷载的建筑物,通常可以采用相对便宜的筏板基础。当差异沉降发生时,足够刚度的基础将使建筑物作为刚体倾斜,并将防止建筑物的显著变形和随之而来的墙壁开裂。本文介绍了倾斜建筑物的一些历史案例,以说明在不同地面条件下观察到的倾斜程度,以及采取的补救措施。可注意性是评估低层住宅建筑及其居住者倾斜度可接受性的关键因素,倾斜度通常在1/250到1/200之间时被注意到。如果测量到的倾斜度为1/100或更大,或测量到的倾斜度增加率表明将超过该倾斜度,…

Settlement and tilt of low-rise buildings
Where deep foundations are not an economically viable solution, foundation problems may occur at low-rise housing developments on poor ground. It is usually feasible to provide a raft foundation relatively cheaply for lightly loaded buildings. When differential settlement occurs, foundations of adequate stiffness will cause the building to tilt as a rigid body, and will prevent significant distortion of the building and consequent cracking of the walls. A number of case histories of tilted buildings are presented to illustrate the magnitude of tilt that has been observed with different ground conditions, and the remedial actions that have been undertaken. Noticeability is a key factor in assessing the acceptability of tilt for low-rise residential buildings and their occupants, and tilt typically is noticed when it is in the region of 1/250 to 1/200. Where tilts of the magnitude of 1/100 or greater are measured, or the measured rate of increase of tilt indicates that this degree of tilt will be exceeded, ...

期刊介绍: The objectives of the Association shall be the promotion of co-operation among geotechnical societies in SE Asia; and the assistance to member societies who have limited number of members. Now there is only one combined web titled: AGSSEA-SEAGS. SEAGS & AGSSEA encourage the submission of scholarly and practice-oriented articles to its journal. The journal is published quarterly. Both sponsors of the journal, the Southeast Asian Geotechnical Society and the Association of Geotechnical Societies in Southeast Asia, promote the ideals and goals of the International Society of Soil Mechanics and Geotechhnical Engineering in fostering communications, developing insights and enabling the advancement of the geotechnical engineering discipline.
