54主城區(qū)“兩江四岸”治理提升嘉陵江岸線貫通工程--嘉濱路大溪溝段結(jié)構(gòu)計算書設(shè)計資料主城區(qū)“兩江四岸”治理提升嘉陵江岸線貫通工程嘉濱路大溪溝段，位于嘉陵江南岸（渝中區(qū)），起點始于洪崖洞，終點至渝澳大橋，岸線全長3.9公里，總面積約34.28公頃。本工程建設(shè)性質(zhì)為更新改造工程，工程內(nèi)容主要有碼頭還綠、排水口提升、垂直擋墻覆綠、灘涂治理、橋下空間改造、消落帶生態(tài)治理、步道、活力道、親水道、彈性道、特色文化節(jié)點、現(xiàn)狀場地提升等。本項目結(jié)構(gòu)計算主要包括樁板式擋墻和重力式擋墻結(jié)構(gòu)計算。設(shè)計依據(jù)《建筑邊坡工程技術(shù)規(guī)范》（GB50330-2013）《公路路基設(shè)計規(guī)范》（JTGD30-2015）《混凝土結(jié)構(gòu)設(shè)計規(guī)范》（GB50010-20102015年版）《混凝土結(jié)構(gòu)耐久性設(shè)計規(guī)范》（GB/T50476－2019）《混凝土結(jié)構(gòu)工程質(zhì)量驗收規(guī)范》(GB50204-2015)擋墻結(jié)構(gòu)驗算根據(jù)景觀步道與現(xiàn)狀建構(gòu)筑物的相互空間關(guān)系，本次結(jié)構(gòu)設(shè)計主要采用樁板擋墻和重力式擋墻進行處理。其中樁板擋墻根據(jù)臨空高度及地質(zhì)條件不同，分別采用A型、B型、C型、D型樁板式擋墻進行處理。由于樁板擋墻均位于嘉陵江沿岸斜坡上，考慮江水長期淘蝕沖刷及水土搬運作用對擋墻的不利影響，樁板擋墻計算時，計算臨空高度按墻前10m襟邊范圍內(nèi)不考慮土體嵌固作用起算。同時根據(jù)地勘報告“由于本項目場地位于重慶主城區(qū)，距離庫區(qū)大壩較遠，水位陡降與陡升可能性小，且岸坡由塊石土組成，土體孔隙較大，滲透系數(shù)大，難以形成穩(wěn)定水頭差的水力坡度線，故考慮工況時不考慮由于水位陡升或陡降形成的動水壓力”，樁計算時按浸水擋墻，前后水位差按1m考慮。根據(jù)地形圖及地勘剖面，本項目各樁型計算控制參數(shù)如下表所示：樁板擋墻結(jié)構(gòu)計算控制參數(shù)表樁型樁徑（mm）嵌巖深度（m）樁間距（m）計算臨空高度（m）A15003.04.06.0B18004.04.08.0C20005.04.010.0D22006.04.012.0樁板擋墻結(jié)構(gòu)驗算A型樁板擋墻計算（φ1500）樁、板計算條件1.總控制信息路基型式路堤地區(qū)類型浸水地區(qū)支護類型樁＋板結(jié)構(gòu)重要性系數(shù)1.00抗震設(shè)計烈度(度)配筋計算水平地震系數(shù)Kh水上地震角(度)水下地震角(度)重要性修正系數(shù)Ci綜合影響系數(shù)Cz2.坡線、土層和水位1)坡線信息坡線數(shù)1坡線水平投影豎向投影坡線長坡線仰角荷載數(shù)序號長(m)長(m)(m)(°)110.0000.00010.0000.0001坡線荷載：荷載荷載類型P1P2X1(m)X2(m)序號(kN,kN/m)(kN/m)1-1分布力5.0005.0000.00010.0002)土層信息樁前是否有橫坡無橫坡樁前橫坡角(度)0.000樁后橫坡角(度)0.000結(jié)構(gòu)與土摩擦角(度)12.500嵌固段以上土層數(shù):1序號地層地層重度浮重度粘聚力內(nèi)摩擦綜合內(nèi)摩土摩阻計算m,c,K承載KHηR類型厚(m)(kN/m3)(kN/m3)(kPa)角(°)擦角(°)力(kPa)方法力(kPa)(MPa)1土層6.00020.50010.5003.00025.000120.000m法8.000120.000嵌固段土層數(shù):4序號地層地層重度粘聚力內(nèi)摩擦綜合內(nèi)摩土摩阻計算m,c,K承載KHηR類型厚(m)(kN/m3)(kPa)角(°)擦角(°)力(kPa)方法力(kPa)(MPa)1土層9.52020.5003.00025.000120.000m法8.000120.0002土層7.96020.20010.00016.000120.000m法30.000140.0003巖層2.14024.2000.00040.000120.000K法20.000350.0000.5000.30010.0004巖層15.00025.5000.00055.000120.000K法100.0001000.0000.5000.30010.0003)水位信息樁前水位標高(m)5.000水面線段數(shù)1水面起點標高(m)6.000折線水平投豎向投坡線長坡線仰序號影長(m)影長(m)(m)角(°)110.0000.00010.0000.0003.計算模型1)樁前覆土模型：彈簧模型4.樁信息1)樁基本信息樁前地面以上長度(m)6.000嵌固點深度(m)0.000懸臂長度(m)6.000嵌固長度(m)22.700截面形狀圓形樁徑D(m)1.500樁中心距(m)4.000樁底支承條件自由坡線數(shù)12)樁配筋信息樁作用綜合分項系數(shù)1.40樁混凝土強度等級C30樁縱筋合力點到外皮距離(mm)100樁容重(kN/m^3~)25.00樁縱筋級別HRB400樁箍筋級別HRB4005.板信息1)板尺寸信息樁間板類型直板樁間板的種類數(shù)1板的搭接長度(m)0.500板類型號板厚(mm)板寬(m)板塊數(shù)13000.600112)板配筋信息板作用綜合分項系數(shù)1.400混凝土強度等級C30鋼筋合力點到邊緣距離(mm)25板縱筋級別HRB400板選筋鋼筋直徑166.結(jié)構(gòu)上自定義荷載以及荷載組合1)樁頂自定義荷載樁頂自定義荷載數(shù)：02)樁荷載組合[庫侖土壓力(一般)組合]荷載號荷載名稱是否參與調(diào)整系數(shù)1樁自重√1.0002樁頂恒載√1.0003樁頂活載√1.0004樁后主動土壓力√1.0005靜水壓力√1.0002)板荷載組合[庫侖土壓力(一般)組合]荷載號荷載名稱是否參與調(diào)整系數(shù)1板后主動土壓力√1.0002靜水壓力√1.000原始條件:庫侖土壓力(一般情況)(一)樁身內(nèi)力計算按實際墻背計算得到:第1破裂角：34.884(度)Ea=64.354(kN)Ex=62.829(kN)Ey=13.929(kN)作用點到嵌固點距離Zy=1.928(m)[水壓力計算]地下水作用水頭及壓強(水頭相對于嵌固段頂端)水頭高(m)樁底水壓(kPa)墻面坡側(cè)：5.00050.000墻背坡側(cè)：6.00060.000第1嵌固段地層計算方法:m法第2嵌固段地層計算方法:m法第3嵌固段地層計算方法:K法第4嵌固段地層計算方法:K法背側(cè)——為擋土側(cè)；面?zhèn)取獮榉菗跬羵?cè)。背側(cè)最大彎矩=2074.915(kN-m)距離樁頂9.443(m)面?zhèn)茸畲髲澗?82.367(kN-m)距離樁頂19.602(m)最大剪力=467.205(kN)距離樁頂6.000(m)最大位移=-21(mm)點號距頂距離彎矩剪力位移土反力(m)(kN-m)(kN)(mm)(kPa)1-0.000-0.000-0.000-21.220.00020.2000.053-0.800-20.770.00030.4000.445-3.477-20.330.00040.6001.589-8.332-19.890.00050.8003.925-15.387-19.450.00061.0007.891-24.644-19.000.00071.20013.875-35.301-18.560.00081.40022.052-46.559-18.120.00091.60032.539-58.418-17.680.000101.80045.459-70.878-17.240.000112.00060.931-83.939-16.790.000122.20079.075-97.601-16.350.000132.400100.011-111.863-15.910.000142.600123.860-126.726-15.470.000152.800150.741-142.191-15.030.000163.000180.776-158.256-14.590.000173.200214.084-174.922-14.150.000183.400250.785-192.189-13.720.000193.600290.999-210.056-13.280.000203.800334.847-228.525-12.850.000214.000382.449-247.594-12.410.000224.200433.925-267.265-11.980.000234.400489.395-287.536-11.560.000244.600548.980-308.408-11.130.000254.800612.799-329.881-10.710.000265.000680.972-351.955-10.290.000275.200753.621-374.629-9.880.000285.400830.864-397.905-9.460.000295.600912.823-421.781-9.060.000305.800999.701-444.355-8.660.000316.0001090.517-467.205-8.26-0.000326.2031184.915-465.905-7.86-12.742336.4051279.175-459.410-7.47-24.222346.6081371.112-446.034-7.09-34.476356.8101459.866-428.257-6.72-43.540367.0131544.601-406.610-6.35-51.456377.2151624.586-381.607-5.99-58.266387.4181699.192-353.742-5.64-64.018397.6201767.889-323.486-5.30-68.759407.8231830.239-291.287-4.97-72.542418.0261885.891-257.571-4.65-75.418428.2281934.582-222.739-4.34-77.441438.4311976.124-187.166-4.05-78.669448.6332010.404-151.201-3.76-79.157458.8362037.377-115.170-3.48-78.962469.0382057.061-79.371-3.21-78.142479.2412069.531-44.074-2.96-76.754489.4432074.915-9.527-2.72-74.854499.6462073.39024.051-2.49-72.500509.8492065.17256.465-2.27-69.7465110.0512050.51687.544-2.06-66.6465210.2542029.707117.145-1.86-63.2535310.4562003.060145.144-1.67-59.6175410.6591970.909171.441-1.50-55.7885510.8611933.608195.961-1.33-51.8125611.0641891.524218.644-1.18-47.7335711.2661845.034239.4
