SECTION – IV 8.0. Discussions, Analysis Recommendation（讨论、分析及建议） Sub-soil conditions and the engineering properties of different layers as revealed by the investigation are described above.（上文介绍了土壤情况和不同土层的工程特性）Aspects of safe bearing capacity and settlement of shallow foundations as well as deep foundation in the form of RCC Bored Cast In-situ Piles are discussed hereunder. (下文讨论混凝土钻孔灌注桩的安全承载力和深、浅基础的沉降情况) Selection of suitable foundation depends on the following factors : (选择合适的基础取决于以下几个因素) 1. Safe bearing pressure on founding soil (土层的承载力) 2. Settlement of foundations should be within allowable limits （地基的沉降应在允许的范围内） 3. Cost of foundation construction （基础的施工成本） 4. Construction aspects e.g. excavation, ground water table etc. （施工方面例如，开挖、施工水位等） INTRODUCTION The borelog data of 16 Nos. of boreholes ( BH - 5, 14, 16, 21, 47, 54, 64, 71, 74, 75, 78, 86, 93, 94, 108, 117), sunk in the locations as directed by client in the proposed Pellet Plant area of Usha Martin-Jamshedpur site, reveal that, the sub-surface stratification at this site varies in terms of depth, thickness compactness of underlying strata.（16个钻孔的柱状图显示：场地下地层的深度、厚度、密实度是变化的）The sequence of occurrence shows that, in general, below the top uncontrolled, erratic, heterogeneous Fill (Stratum-I), there exists a stiff to very stiff, yellowish brown, silty Clay layer (Stratum -II) overlying a brownish yellow, dense to very dense, residual, silty Sand layer (Stratum-III). (地层-I是不稳定、非均质的填土，地层-II是僵硬、黄棕色的粉质粘土层，地层-III上是棕黄色、非常密实的、残余的粉砂层) This is followed by a highly weathered, disintegrated, decomposed, brownish yellow, mica-schist rock layer (Stratum-IV) continued upto the maximum depth of exploration.(地层-IV：高度风化，分解，呈棕黄色云母片岩岩石层，并一直持续到勘探最深处) For depth thickness of different strata, at different borehole locations, as obtained during investigation, the attached bore logs may be referred. It is learnt that, the final Terrace Level (TL) of the subject area is 158.5 m. （场地±0.00相当于绝对标高158.5m）During investi
