in 100m away from construction site for the water used for construction work, at present, no life water ring work is established, party A shall provide interface as near as possible within life zone, the following part will be on us 14 / 90、臨時(shí)道路 Temporary road現(xiàn)有一條臨時(shí)道路進(jìn)入施工區(qū)域附近,進(jìn)場后需要從該道路引接一條施工道路到達(dá)取水泵房、頂管等施工場地。 12 / 90Daily change range of relative humidity 32%年平均相對濕度 %Average relative annual humidity最高大氣壓力 1065hPaHighest atmospheric pressure最低大氣壓力 955hPaLowest atmospheric pressure、降雨量 Rainfall 平均降雨量: 3759 mm (19512022)Average rainfall年最大降雨量: 4692 mmHighest annual rainfall年最小降雨量: 2900 mmLowest annual rainfall日最大降雨量: 222 mmHighest daily rainfall月平均降雨量(1951-2022)Average monthly rainfall項(xiàng)目item 月份Month1 2 3 4 5 6降雨量 (mm)Rainfall416 268 272 251 231 259項(xiàng)目Rainfall月份Month7 8 9 10 11 12降雨量 (mm)Rainfall250 282 309 358 415 44風(fēng)向頻率 Wind direction frequency根據(jù)民都魯(BINTULU)機(jī)場氣象站 1975 年~2022 年共 28 年風(fēng)向頻率資料統(tǒng)計(jì), 30 年最大風(fēng)速為 31 m/s.13 / 90According to wind direction frequency statistics of BINTULU airport weather station during 19752022, highest wind speed is 31 m/s in 30 years 、地震烈度 seismic intensity地震水平加速度 Seismic horizontal acceleration 、淡水供應(yīng) fresh water supply電廠淡水水源來自城市生活飲用水管網(wǎng)。Mostly, the underwater level in the same hole in the planed site varies no much, only a few holes are exceptional, probably due to precipitation. On plane, the underwater level of all the holes are various in burying depth, the shallowest (see geological survey document of accessory buildings section), the deepest (see geological survey document of circulating water pipe section ). 、氣候條件 Climatic condition電站地處海邊的熱帶區(qū)域,氣候炎熱,空氣潮濕、含鹽霧。 seawater has a medium corrosion to both the steel bars in concrete structure and to steel 11 / 90structure. 擬建場地同一孔中地下水位的大部分變幅不大,個(gè)別孔中的地下水位變幅較大,估計(jì)是受大氣降水影響所致。場地地下水對混凝土結(jié)構(gòu)中的鋼筋無腐蝕性,對鋼結(jié)構(gòu)具有弱腐蝕性;海水對混凝土結(jié)構(gòu)、對混凝土結(jié)構(gòu)中的鋼筋及鋼結(jié)構(gòu)均具有中等腐蝕性。The strength of the foundation soil layer distributed within 020m depth range in circulating water pump rooms section, preliminarily designed pumps room base is located on the fine silt in highdense layer (43)with good construction ability, according to the position of foundation soil and site condition, the lower structure of circulating water pumps room can be constructed in the way of sunk well(as the underwater of this section buried in a shallow depth, pit walls produced by big excavation are all sand layer, although it has a good pactness, occasionally soaking by water is still possible to create drifting sand then to collapse), during construction work, appropriate and feasible level lowering and water draining measure should be taken, based on our pany’s construction experience in sunk wells under all classes of geological condition, foundation pit water level lowering of this project can be realized in the bined way of well water level lowering and insidepit water draining to strictly prevent socking of pit wall 、水文條件 hydrological condition、海水標(biāo)高 Sea water elevation最低天文潮位 (LAT)lowest astronomical tide level m平均較低水位 (MLLW)Average low water level m平均海平面 (MSL )Average Seal Level m平均較高的高水位 (MHHW)Average Higher High Water Level m10 / 90最高天文潮位 (HAT) Highest Astronomical Tide Level m、 海水溫度 Sea water temperature最高日平均溫度 : 33 ℃Highest average daily temperature最低日平均溫度 : 25 ℃Lowest average daily temperature日平均溫度 : ℃Average daily temperature設(shè)計(jì)冷卻水溫取 31℃,最高水溫 34 ℃。As the upper earth of the planed site’s foundation is soft, the underwater is buried in a shallow depth, when foundation pit is excavated, the pit wall section consisted of the layer(21)is easy to collapse, Layer (31) amp。The fine silt layers (31)amp。Buried foundation rock is french gray or clay fine silt offwhite, usually contains thin layer of sandy clay rock. According to the status of weathering, the buried foundation rock is divided into strongly weathered layer(61) and medium weathered layer(62). 8 / 90Layers (61 )are mostly weathered into sandy condition, it is hard to take out a plete rock core, normally layer thickness is 。根據(jù)其風(fēng)化程度,將下伏基巖劃分為(61)層強(qiáng)風(fēng)化層和(62)層中等風(fēng)化層。Layer (54)Silty clay shows hard plastic condition, its construction ability is good, but this two layers are buried in deeper depth.(61)層強(qiáng)風(fēng)化泥質(zhì)粉細(xì)砂巖及(62)層中等風(fēng)化泥質(zhì)粉細(xì)砂巖的建筑性能良好,但埋藏較深。Layer (42)fine silt shows dense, with the characteristics of low pressibility and high bearing capability, its construction ability is high. All the above layers are not consecutive, and widely vary in thickness.(43)層很密的粉細(xì)砂層亦具良好的建筑特性,但埋藏較深。該層大部分地段分布厚度較大;Layer (35)fine silt layer in high density mostly shows selfbinding condition, it has a good workability. Most section of this layer is thick.(41)層粉細(xì)砂呈中密狀,具中等壓縮性、承載力中等的工程特性,其建筑性能一般;Layer (41)fine silt shows mediumdense, it has a medium pressibility, and medium bearing capability, ordinary construction ability.(42)層粉細(xì)砂呈密實(shí)狀,具低壓縮性、承載力較高的工程特性,其建筑性能良好。上述各層分布均不連續(xù),層厚變化較大。This project is located nearby South China Sea, the site and the surrounding is covered by sediment and swamp sediment, the sediments are consist of sands, viscous sandy soil and soft clay. 場地土類別:II 類。The plant is located at 500m away from the coast of South China Sea which is very near from BINTULU port, transportation distance is about 6km, its topography is flat.、工程地質(zhì)及水文條件 Geological and hydrological conditions、工程地質(zhì) 5 / 90Geological condition該工程現(xiàn)場位于南中國海邊,現(xiàn)場和周圍環(huán)境為近岸沉積物和沼澤沉積物所覆蓋。This project is located in BINTULU, Sarawak state, east Malaysia, this extension is to build 2 new residual heat boiler, 1 turbinegenerator unit and relevant accessories based on the original two sets (7 amp。1 / 90馬來西亞民都魯 209E 聯(lián)合循環(huán)電站工程Malaysia B
