| 摘 要： | 徐州市区岩体可分碎屑岩(碎屑硬质岩、碎屑软质岩)及碳酸盐岩(碳酸盐岩碎屑岩硬质与软质岩互层、碳酸盐岩硬质岩)。土体可分为砂土类、粉土类和粘性土(新粘性土、老粘性土)。根据各类土体物理力学性质的分析可知,基岩和老粘土一般可作为高层建筑持力层。一般砂土、粉粘土、粉土等可作一般建筑物地基。对易液化的砂性土、淤泥质软土则需做一定的地基处理。

| Abstract: | There are two types of rock mass in Xuzhou downtown area,which are clastic rock(hard clasolite and weak clasolite)and carbonate rock(hard carbonate rock and weak rock aternate layer,hard carbonate rock). Soil body can be divided into ore soil,mealy soil and cohesive soil(fresh cohesive soil,former cohesive soil). According to its physical mechanic property,bottom rock and former cohesive soil generally used as supporting course of high-rise. Ore soil,mealy soil and mealy cohesive soil usually used as foundation structure. Determinate foundation treatment is necded for liguefacient cohesionless soil and weak sullage soil. |
