万福路（K2+360～K3+070）桥梁段设计高边坡计算书

设计资料根据道路设计，本工程在道路桩号K2+360.000～K2+415.500左右两侧；K2+955.000～K3+070.000段道路左侧；以及K2+975.000～K3+030.000右侧产生高边坡，其最大挖方高度约29.5m，最大填方高度约11.0m。由于道路两侧放坡均不受限，以上部位高边坡均采用坡率法放坡的方式实施。设计依据《建筑边坡工程技术规范》（GB50330-2013）《公路路基设计规范》（JTGD30-2015）《混凝土结构设计规范》（GB50010-2010）(2015年版)边坡稳定性验算填方边坡边坡坡率法放坡圆弧滑动稳定性计算[计算简图][控制参数]:采用规范: 通用方法计算目标: 安全系数计算滑裂面形状:圆弧滑动法不考虑地震[坡面信息]坡面线段数4坡面线号水平投影(m)竖直投影(m)超载数112.2507.000022.0000.0000312.0008.0000416.0000.0003超载1距离0.010(m)宽4.000(m)荷载(5.00--5.00kPa)270.00(度)超载2距离4.000(m)宽8.000(m)荷载(20.00--20.00kPa)270.00(度)超载3距离12.000(m)宽16.000(m)荷载(5.00--5.00kPa)270.00(度)[土层信息]上部土层数1层号层厚重度饱和重度粘聚力内摩擦角水下粘聚水下内摩十字板强度增十字板羲强度增长系全孔压(m)(kN/m3)(kN/m3)(kPa)(度)力(kPa)擦角(度)(kPa)长系数下值(kPa)数水下值系数115.00020.0000.00035.000下部土层数2层号层厚重度饱和重度粘聚力内摩擦角水下粘聚水下内摩十字板强度增十字板羲强度增长系全孔压(m)(kN/m3)(kN/m3)(kPa)(度)力(kPa)擦角(度)(kPa)长系数下值(kPa)数水下值系数12.00020.0000.00028.000240.00024.000376.00032.000不考虑水的作用[计算条件]圆弧稳定分析方法:Bishop法土条重切向分力与滑动方向反向时:当下滑力对待稳定计算目标:(null)条分法的土条宽度:1.000(m)圆弧入口起点x坐标:31.250(m)圆弧入口终点x坐标:36.000(m)圆弧出口起点x坐标:-5.000(m)圆弧出口终点x坐标:0.000(m)搜索时的圆心步长:1.000(m)入口搜索步长:1.000(m)出口搜索步长:1.000(m)搜索圆弧底的上限:1000.000(m)搜索圆弧底的下限:-1000.000(m)圆弧限制最小弓高:1.000(m)计算结果:最不利滑动面:滑动圆心=(2.037,34.296)(m)滑动半径=35.011(m)滑动安全系数=1.501起始x终止xliCi謎条实重浮力地震力渗透力附加力X附加力Y下滑力抗滑力m鑙(m)(m)(度)(m)(kPa)(度)(kN)(kN)(kN)(kN)(kN)(kN)(kN)(kN)5.000-4.000-10.7621.020.0028.001.900.000.000.000.000.00-0.351.100.91613-4.000-3.000-9.1001.010.0028.005.400.000.000.000.000.00-0.853.080.93127-3.000-2.000-7.4461.010.0028.008.310.000.000.000.000.00-1.084.670.94556-2.000-1.000-5.7981.010.0028.0010.630.000.000.000.000.00-1.075.900.95902-1.000-0.000-4.1561.000.0028.0012.380.000.000.000.000.00-0.906.770.971650.0000.907-2.5920.910.0028.0016.970.000.000.000.000.00-0.779.180.982920.9071.815-1.1060.910.0028.0026.910.000.000.000.000.00-0.5214.410.992961.8152.7220.3790.910.0028.0036.420.000.000.000.000.000.2419.321.002332.7223.6291.8640.910.0028.0045.510.000.000.000.000.001.4823.931.011023.6294.5373.3510.910.0028.0054.170.000.000.000.000.003.1728.261.019044.5375.4444.8400.910.0028.0062.400.000.000.000.000.005.2632.321.026385.4446.3526.3320.910.0028.0070.200.000.000.000.000.007.7436.131.033056.3527.2597.8290.920.0028.0077.560.000.000.000.000.0010.5639.691.039037.2598.1669.3300.920.0028.0084.480.000.000.000.000.0013.7043.011.044328.1669.07410.8390.920.0028.0090.960.000.000.000.000.0017.1146.111.048919.0749.86812.2600.810.0035.0084.580.000.000.000.000.0017.9655.021.076469.86810.66213.5930.820.0035.0088.890.000.000.000.000.0020.8957.531.0818610.66211.45614.9340.820.0035.0092.890.000.000.000.000.0023.9459.851.0867011.45612.25016.2840.830.0035.0096.580.000.000.000.000.0027.0861.981.0909612.25012.91717.5330.700.0035.0081.150.000.000.000.000.0024.4551.921.0943712.91713.58318.6810.700.0035.0078.250.000.000.000.000.0025.0649.941.0970513.58314.25019.8360.710.0035.0075.140.000.000.000.000.0025.5047.861.0993014.25015.17321.2270.990.0035.00104.190.000.000.000.000.0037.7266.241.1014115.17316.09622.8571.000.0035.00108.650.000.000.000.000.0042.2068.971.1030616.09617.01924.5071.010.0035.00112.530.000.000.000.000.0046.6871.391.1038217.01917.94226.1781.030.0035.00115.820.000.000.000.000.0051.1073.481.1036617.94218.86527.8741.040.0035.00118.490.000.000.000.000.0055.4075.251.1025418.86519.78829.5981.060.0035.00120.500.000.000.000.000.0059.5276.681.1004019.78820.71231.3511.080.0035.00121.830.000.000.000.000.0063.3977.751.0972120.71221.63533.1371.100.0035.00122.440.000.000.000.000.0066.9378.441.0929121.63522.55834.9611.130.0035.00122.280.000.000.000.000.0070.0778.741.0874122.55823.48136.8261.150.0035.00121.300.000.000.000.000.0072.7178.601.0806623.48124.40438.7381.180.0035.00119.450.000.000.000.000.0074.7577.981.0725424.40425.32740.7031.220.0035.00116.640.000.000.000.000.0076.0776.841.0629625.32726.25042.7281.260.0035.00112.800.000.000.000.000.0076.5475.101.0517726.25027.25044.9121.410.0035.00109.860.000.000.000.004.9581.0677.431.0382427.25028.25047.2731.470.0035.0089.070.000.000.000.005.00
