哈哈，一号球衣的好点子，给买主卖主们多找了件操心的事 咱们不是刚讨论过，无知者无畏吗？

对我而言，不知者更畏阿

粘土不一定坏，砂土也不一定好。硬的粘土，跟石头似的，用镐砸下去，只砸出个指甲盖大的印子。粘性土的强度和它的含水量关系很大，所以在描述粘性土的时候，常会提一下它的状态，也就是它的含水量在哪个范围里面。报告中的描述是stiff和very stiff，说明含水量不高。

我就是搞不清这个到底含水量多少了才会对silty clay 有影响。这个Sales 给了我整个的report, 外加钻孔图，但是好像离我lot 近的那个test pit 查出来并不是很硬。我在网上看到说一般承受力要大于75 kilopacal. 但是这有些地方才40 - 50。
Sensitive silty Clay
This silty clay extends to depths ranging from about 1.5 metres (test pit 03-16) to at least 5.5 metres (test pit 3-12) below existing ground surface. The upper portion of the silty clay has been weathered to a stiff grey brown crust. The weathered zone extends from approximately 3.1 metres to 5.0 metres below the existing ground surface, or to the full depth of the weathered crust gave undrained shear strengths ranging from 90 kilpascals to greater than 130 kilopascals (the limit of the vane apparatus), which indicates a stiff to very stiff consistency. The measured water contents of two samples of the weathered silty clay were approximately 22 and 44 percents.
The silty clay below the depth of weathering is grey in colour. The grey silty clay were encountered at all of the test pit locations except at test pits 03-4, 03-15, 04-16, 03-17, 03-18 and 03-19, where is is either absent or the depth of weathering exceeds the depth of the test pits. The results of in situ vane testing carried out in the grey silty clay gave undrained shear strengths ranging from 40 to 100 kilpoascals, indicating a firm to very stiff consistency. The measureed water contents of two samples of the grey silty clay were approximately 42 and 59 percent.

泡泡手里只有这个表吗？是不是还有张钻孔平面，标出这三个孔的位置？从地表标高看，地势稍有起伏，从土层看，差异挺大。

有图，贴在下面了

粘土层的强度不算低，若单算承载力，盖个小木房是绰绰有余。粘土下面的Till，一般都算是挺理想的土层。另一个好消息是，三个孔里面都没见到地下水，就是说那片地方，在钻孔的那个季节，地下五米之内没水。

report 上还有说Corrosion and Cement type.
Two samples of soil from pit 3-9 and 3-16 were submitted to XXX lab for chemical analysis related to potential corrosion of buried steel elements and potential sulphate attack on buried concrete elements。The results of this testing are provided in Appx A. The results indicated that concrete made with Type 10 Portland cement should be acceptable for substructures. The results also indicate a high potential for corrosion of exposed ferrous metal.
请问这个ferrous metal 是正常的吗，对人体会有影响吗.
再次感谢楼主，真是专家阿
