Thecontinuous observation of the water level in the boreholes in 24 hours shows that the water level varies by 1.0m in one day. Generally, the ground water level is changed

50、within 3 hours after the tide changes. During the investigation the measuredwater WuSonbevel wasfrom 2.62.9 m. According to the relevant codes of Shanghai, the usual water embedment depth is 0.5m.通過(guò)對(duì)現(xiàn)場(chǎng)采取的83只水樣進(jìn)行Cl-及SO42-?分析,Cl-含量在65.3mg/L5621mg/L之 問(wèn)，SO42-?含量在275mg/L1390mg/L之間，水質(zhì)變化受潮汐水動(dòng)態(tài)及大氣降水、蒸發(fā)影響。場(chǎng)地

51、內(nèi)地下水PH值在7.88.2之間。A total of 83 water samples were taken andSOz2-?analysis were done on them. The result shows that Cl content is from 65.3mg/L to 5621mg/L, S?4ontent is from 275mg/L to 1390mg/L. The water quality is affected by the tides of Hangzhou Bay, rainfall and evaporation. PH value is from 7.

52、8 to 8.2.場(chǎng)地及附近未發(fā)現(xiàn)地下水污染源存在，根據(jù)現(xiàn)場(chǎng)采取的4組地下水樣進(jìn)行水質(zhì)分析的結(jié) 果，可判定：本場(chǎng)地淺部地下水對(duì)碎無(wú)腐蝕性，對(duì)鋼結(jié)構(gòu)具中等腐蝕性。No underground water pollution source was found in and nearby the Site. Judging from the water quality analysis on the 4 water samples taken from the site we can say that the shallow water is not to weak corrosi to concr

53、ete, but it has medium to weak corrosivity to steel structure.地震動(dòng)峰值加速度(或地震基本烈度)、場(chǎng)地類(lèi)別及液化判定Basic seismicintensity, seismic type of the Site, and liquefaction analysis根據(jù)有關(guān)規(guī)范：本場(chǎng)地屬I(mǎi)V類(lèi)場(chǎng)地，地震動(dòng)峰值加速度為0.05g(相當(dāng)于地震基本 烈度6度)。本場(chǎng)地地基土可不考慮砂土液化問(wèn)題。According to the relevant standards, the site is thought to be Type IV an

54、d the peak value of seismic acceleration is 0.05g (equal to 6 degree basic seismic intensity). The seismic liquefaction need not be taken into consideration for this site.鑒于本工程的特殊性，業(yè)主要求部分主體項(xiàng)目場(chǎng)區(qū)按地震烈度7度進(jìn)行地震液化評(píng)價(jià)。場(chǎng)地20m以淺分布有成層飽和的3-1層砂質(zhì)粉土，根據(jù)現(xiàn)場(chǎng)標(biāo)準(zhǔn)貫入試驗(yàn)成果， 結(jié)合室內(nèi)顆粒分析指標(biāo)，按照規(guī)范綜合判定：地基土在地震烈度7度條件下，不會(huì)發(fā)生砂土液化。(液化判定計(jì)算結(jié)果見(jiàn)

55、表 5) oTaken the particularity of the project into consideration, the Client requires that the seismic liquefaction of the main project zones should be evaluated at 7 degree. Stratum 3-1 on the site is saturated sandy silt within the depth of 20m. Based on the results of the SPT on site, the grain si

56、ze analysis test in lab, and the relevant codes, it can be concluded that no sand liquefactioncan happen on the Site when the seismic intensity is at 7 degree.(Please refer to Table 5 for the liquefaction result).Table 5標(biāo)準(zhǔn)貫入試驗(yàn)液化判別表Liquefaction analysis based on SPTvalue孔號(hào)Nr of層號(hào)Nr of地下水 埋深標(biāo)貫 深度粘粒 含量
