with a thickness from 1.35 to 2.70m. The soil should be treated by ways of rolling or dynamic consolidation and if necessary Stratum ②3-1 can also be used as the sustaining layer of the natural foundation.

根据场地工程地质资料，对上述各建筑物的天然地基基础中心点最终沉降量估算，见表3.4.2。

Based on the engineering geological data of the Site the calculation of the final settlement of the center of the natural foundation for the proposed buildings was worked out, as shown in Table 3.4.2.

Table 3.4.2 Calculation of final settlement of foundation center

罐径为Φ7.5m,H=12m,容积为500m3，基底荷载120kPa，基础容许沉降量150mm。 The tank has a volume of 500m3 is 7.5m in diameter and 12m in height. Foundation load is 120kPa, and the foundation allowable settlement is 150mm.

拟建场地浅部分布的②3-1层砂质粉土，物理力学性质较好。当拟建各罐采用以②3-1层土为基础持力层的天然地基，地基土承载力及沉降控制均可满足要求。基础砌置标高1.30左右，对局部吹填土较厚地段采用夯实或压客注浆法进行地基加固处理。必要时，采用加固深度至⑤1-1层的碎石桩对整个罐区地基进行加固处理；或以 ⑤1-1层为持力层的桩基础，采用350×350预制桩或Φ400PHC管桩。

The Stratum ②3-1 distributed in the shallow surface of the Site has good physical and mechanic features. If the proposed tanks use Stratum ②3-1 as its natural foundation’s sustaining layer, the bearing capacity of the foundation and its settlement control can meet the
