48、按中線和邊線交錯(cuò)布置。(3)興隆湖14號(hào)路共布設(shè)鉆孔20點(diǎn)，勘探點(diǎn)編號(hào)14zk114zk20。勘探點(diǎn)沿道路走向間距50m，按中線和邊線交錯(cuò)布置。(4)廣西路共布設(shè)鉆孔26點(diǎn)，勘探點(diǎn)編號(hào)gx11gx26。勘探點(diǎn)沿道路走向間距50m，按中線和邊線交錯(cuò)布置。2.3.2水文本項(xiàng)目圍繞興隆湖而建，規(guī)劃要求，興隆湖常水位標(biāo)高為464m。經(jīng)勘察本路段地表水主要為老舊魚塘積水及農(nóng)田排水灌溉渠水。路段地下水主要為賦存于低洼地段白堊系上統(tǒng)夾關(guān)組砂質(zhì)泥巖中的風(fēng)化裂隙水，其主要補(bǔ)給來源為大氣降水。風(fēng)化裂隙為主要含水層，其水量受匯水情況及裂隙發(fā)育程度的影響一般較小，流通性較差。場(chǎng)地內(nèi)地下水因含水介質(zhì)的差異和賦水空間的不

49、同，可分為松散土層孔隙水和基巖裂隙水，主要接受大氣降水及地表水的補(bǔ)給，基巖裂隙水還接受松散土層孔隙水的補(bǔ)給。1松散土層孔隙水：區(qū)內(nèi)填土層結(jié)構(gòu)松散，空隙大，滲透性較好，有利于地下水的徑流、補(bǔ)給和賦存，而粉質(zhì)粘土、全風(fēng)化基巖，空隙小，滲透性微弱，不利于地下水的運(yùn)移，起到相對(duì)隔水的作用。2基巖裂隙水：場(chǎng)地基巖裂隙水主要賦存于基巖的淺部風(fēng)化裂隙之中?；鶐r裂隙水含水層賦水性較差，具不均一性，其強(qiáng)風(fēng)化帶及斷裂帶巖層導(dǎo)水性、徑流、排泄條件相對(duì)較好。根據(jù)區(qū)域水文地質(zhì)資料，成都地區(qū)平水期46月，豐水期79月，其余月份為枯水期。2.3.3地下水和土腐蝕性本次勘察在場(chǎng)地內(nèi)的水溝、魚塘中取得的3件地表水試樣，擬建場(chǎng)地

50、環(huán)境類別按ii類，根據(jù)公路工程地質(zhì)勘察規(guī)范（jtg c20 2011）附錄k“水和土的腐蝕性評(píng)價(jià)”k.0.2條，相關(guān)地表水和場(chǎng)地土腐蝕性評(píng)價(jià)如下：1、 按環(huán)境類型水土對(duì)混凝土具微腐蝕性（環(huán)境類別按ii類）；2、 按地層滲透性水對(duì)混凝土具微腐蝕性（地層滲透性為b）；3、 該地下水及土(僅以ph值)對(duì)鋼筋混凝土結(jié)構(gòu)中鋼筋具微腐蝕性。2.3.4氣象場(chǎng)地所處成都地區(qū)屬亞熱帶季風(fēng)型氣候，其主要特點(diǎn)是：四季分明、氣候溫和、雨量充沛、夏無酷暑、冬少冰雪。主導(dǎo)風(fēng)向?yàn)閚ne向，常年平均風(fēng)速為1.2m/s，年平均風(fēng)壓140pa，最大風(fēng)壓約250pa，年平均降雨量為9001000mm，七、八月份雨量集中，易形成暴雨

51、。根據(jù)成都?xì)庀笈_(tái)觀測(cè)資料，成都地區(qū)的氣象指標(biāo)如下：1)氣溫：多年平均氣溫16.2，極端最高氣溫38.3，極端最低氣溫-5.9。2)降水量：多年平均降水量為947.00mm。最大日降水量為195.2mm。3)蒸發(fā)量：多年平均蒸發(fā)量1020.5mm。 4)相對(duì)濕度：多年平均為82。 5)日照時(shí)間：多年平均為1228.3小時(shí)。6)風(fēng)向與風(fēng)速：主導(dǎo)風(fēng)向?yàn)閚ne向，多年平均風(fēng)速為1.35ms。7)最大風(fēng)速為14.8ms(ne向)，極大風(fēng)速為27.4ms(1961年6月21日)。2.4工程特點(diǎn)（1）路床挖填方量大，最大挖深為10m，最深填方為9.0m。（2）挖方段為土質(zhì)路基時(shí)，必須對(duì)路基設(shè)計(jì)標(biāo)高下80cm

52、范圍內(nèi)用級(jí)配砂礫石換填處理。（3）施工現(xiàn)場(chǎng)內(nèi)有鄉(xiāng)鎮(zhèn)道路，道路較窄，不利于施工車輛進(jìn)出，但本工程路基土質(zhì)承載力較好，路基土方挖填完工后，可做為施工及社會(huì)車輛便道，同時(shí)做好路基與鄉(xiāng)村便道的順接。（4）施工現(xiàn)場(chǎng)內(nèi)有大量藕塘、魚塘，是屬于常年積水的洼地，排水困難，路基處理困難。（5）工期緊，筑路材料多為泥巖、又逢雨季施工，有的地段為魚塘等軟基處治，故對(duì)天氣的要求特別高。工后沉降對(duì)路基質(zhì)量的要求高、難度大，應(yīng)在一定的填土高度后實(shí)施沖擊碾壓或強(qiáng)夯，來提高路基強(qiáng)度，減少沉降量。3施工布置3.1施工生產(chǎn)、生活營地布置根據(jù)本工程的施工特點(diǎn)、圍湖施工，其范圍寬及施工中間距離拉得長(zhǎng)，我分部計(jì)劃在施工現(xiàn)場(chǎng)相對(duì)集中地海

53、南路和廣西路設(shè)置1個(gè)施工生產(chǎn)生活營地（具體位置在煎茶鎮(zhèn)青松村1社搬遷后空置民房，樁號(hào)約為k0+120左側(cè)），利用原來修建2棟2層民房，為現(xiàn)場(chǎng)班組人員提供工作、生活場(chǎng)所，使用面積為900m2。一分部駐地設(shè)在煎茶鎮(zhèn)柳溪路一段71號(hào)，租用的當(dāng)?shù)卮迕衩穹?棟，設(shè)置的項(xiàng)目辦公室、管理人員營地，面積約600m2。兩處營地面積共約1500m2，完全能滿足本項(xiàng)目施工人員生產(chǎn)和生活需要。3.2施工用電及用水（1）施工供水本工程供水計(jì)劃采用以下方式：由于施工范圍周邊有鹿溪河通過，加上成都平原地下水豐富，工程施工用水可就近打井直接抽取或抽取鹿溪河水，滿足施工用水需要；施工用水輸水管道布置避開建筑物施工區(qū)，靠近交通道

54、路，并適應(yīng)地形條件、縮短線路、減少工程量，配水干管采用枝狀布置。生活用水，項(xiàng)目駐地是采用的自來水，班組駐地利用原來民房所打的水井抽水。個(gè)別地段既無城市供水管網(wǎng)，附近又無水源的，采用灑水車供水或擇地修建蓄水池保證施工用水。各營地的出入口均設(shè)置車輛沖洗設(shè)備（4人輪流值班全天24小時(shí)）。（2）施工供電由于興隆湖周邊道路均為土石方工程，施工用電基本不用（管網(wǎng)井池全部采用指定的預(yù)制產(chǎn)品），用電較分散，用電負(fù)荷小，只有在興隆湖14號(hào)路匝道施工用混凝土擋墻澆筑，因此施工用電考慮采用30kw的移動(dòng)式柴油發(fā)電機(jī)供電，在根據(jù)各條路施工情況配置12臺(tái)發(fā)電機(jī)，就可滿足施工的需要。3.3道路保通3.3.1 道路改道保通

55、的必要性根據(jù)設(shè)計(jì)圖紙，經(jīng)過對(duì)周邊道路沿線進(jìn)行考察：海口路和興隆湖14號(hào)路由天府路和紅星路干線通過，局部利用現(xiàn)環(huán)湖道路的施工通道；廣西路和海南路有在建的貨運(yùn)大道和煎茶鎮(zhèn)譚家溝村村道公路可以進(jìn)入，這兩條路周邊還有原有修建并且硬化的從興隆鎮(zhèn)至煎茶鎮(zhèn)鎮(zhèn)的鄉(xiāng)村砼道路通過，并且已經(jīng)形成路網(wǎng)。據(jù)現(xiàn)場(chǎng)調(diào)查這些道路大部分當(dāng)?shù)卮迕襁€在使用，但是要通過大型機(jī)具及載貨車輛，來滿足工程需要，必須先打通這兩條路的縱向便道，才能晚餐土石方棄方工作。3.3.2 改道保通道路設(shè)計(jì)改道保通道路利用原有砼村道進(jìn)行拓寬，這樣可以節(jié)約造價(jià)。經(jīng)過現(xiàn)場(chǎng)測(cè)量和踏勘，修筑一條長(zhǎng) m，路面寬7m，路基寬8m的縱向干線+橫向連接線便道，結(jié)構(gòu)型式級(jí)

56、配碎石道路，道路采用80cm厚砂礫石填筑。為了保證線型和路面高程控制，路基以下填方段采用土方分層填筑并碾壓密實(shí)填筑至路基底高程，挖方段，開挖至路基地面高程后，壓實(shí)基礎(chǔ)面，然后進(jìn)行路基級(jí)配砂礫石層填筑。保通道路斷面見下圖：改路工程數(shù)量見下表：改路工程數(shù)量表開挖土方m土方填方m級(jí)配砂礫石m3.3.3 圍擋及指示標(biāo)志在疏解道路施工之前，先在外側(cè)按照市政工程要求沿線采用尺寸2.2m*3m的圍擋全線打圍，將施工區(qū)和外界隔離，圍擋基礎(chǔ)采用人工開挖0.3*0.3*0.3的坑，圍擋固定后澆筑c20砼，圍擋背后采用40角鋼每隔5m做一道支撐。并在道口兩側(cè)采用金屬材質(zhì)設(shè)置警示標(biāo)志牌和指示標(biāo)示牌，道口兩側(cè)設(shè)置警示燈和防撞桶，標(biāo)志牌基礎(chǔ)采用人工開挖0.5*0
