[摘要] 蘇州地下空間項(xiàng)目為二層全埋式地下室框架結(jié)構(gòu)，平面尺寸為190m×112m，采用有限元法對超長結(jié)構(gòu)進(jìn)行了詳細(xì)的溫度應(yīng)力分析，并提出對于超長結(jié)構(gòu)無縫設(shè)計(jì)的分析方法和解決方案；利用有限元法對擋土墻結(jié)構(gòu)進(jìn)行詳細(xì)分析，提出擋土墻底部的雙向受力特征，指出僅考慮單向受力時(shí)，底部偏于不安全；基礎(chǔ)設(shè)計(jì)與基坑開挖整體考慮，提出對全埋式地下空間項(xiàng)目，平板式筏基具有更好的便利性和經(jīng)濟(jì)性。

Abstract: Suzhou underground space structure project is a frame structure, and the plan size is 190m×112m. Thermal stress analysis of the plate was proposed with the FEM method. The analytical method and solution were proposed to solve ultra long structure. Based on the result of the wall FEM, it points out that the wall near the bottom has bi-directional feature, the unidirectional action result is unsafe. Foundation design was considered with the foundation pits. It points out that slab-foundation has more economy and convenience.
Keywords: ultra long structure; thermal stress; foundation design
