[提要] 介紹了西安電視塔場地的地質(zhì)構(gòu)造、地基方案的選擇、基礎(chǔ)設(shè)計及沉降觀測結(jié)果。長達13年之久的沉降觀測結(jié)果表明，絕對沉降值和相對沉降值均接近規(guī)范允許值，西安電視塔采用天然地基是經(jīng)濟合理的。
[關(guān)鍵詞] 電視塔 天然地基 絕對沉降 相對沉降This article introduces the geologic structure of the site, the choice of the foundation project, the base
design and settlement observation results of Xi'an TV Tower. Outcomes of thirteen years survey of the
settlement indicate that the adoption of a natural base for Xi'an TV Tower is economical and rational, as its absolute settlement and relative settlement both come near to regulation permission.
