清溪镇农村移民安置区房屋安全隐

患整治及人居环境综合整治工程—-房屋居住安全工程（边坡整治）抗滑桩扳挡墙边坡结构计算书1、工程概况该工程位于涪陵区清溪街道办事处交巡警旁，由滑坡及场平边坡组成。根据地面调查：滑坡位于场地西南侧，滑坡段因该段地形较陡,在长时间连续降雨下，降低了岩土体力学性质，斜坡开始出现变形拉裂，前缘条石挡墙出现局部的鼓胀及开裂现象，现滑坡体已处于缓慢的滑动阶段。该滑坡从平面上看呈“U”形态，横宽约60m,纵长约28m,后缘至DL1、DL3、DL4一线，高程为289.0~293.0m,滑坡前缘剪出口高程为190.02~203.72m,前后缘高差约13.2m；主滑方向约316°,水平投影面积约1438..6m2；滑体厚0.3〜6.9m,滑坡体的平均厚度约为3.601,估算滑坡的总体积约为0.52）＜10|1113,该滑坡为浅层小型滑坡，工程重要性等级为一级，安全等级为一级。场平边坡位于场地东北侧，场平高程为195.50m,边坡长约83m,坡高6.2-9.1m,为土质边坡、岩土混合边坡，工程重要性等级为一级，安全等级为一级。2、勘察区自然地理条件气象条件勘察区属亚热带湿润季风气候，具有四季分明、雨量充沛、无霜期长、湿度大、春旱、夏热、秋多绵雨、冬干多雾的特点。据涪陵区气象资料，多年平均气温18.17°C,极端最低气温T.5°C（1977年1月29日），最高气温43.5°C（2006年8月15日）。多年平均降雨量为1104mm,但雨量在时间上分布不均，5-9月降雨量约占全年的65-70%,且多大雨、暴雨，最大年降雨量为1600mm,最小年降雨量为823nlln,多年最大日平均降雨量为127mm。勘察区及附近地表无常年性流水及泉眼。交通位置勘察区为涪陵区清溪街道办事处交巡警旁，有道路直达，勘察场地交通较方便。3、地质环境条件地形地貌场地处于风化剥蚀丘陵地貌区，地形总体由南向北倾斜，地形起伏较大。场地内最高高程点206.30m,位于勘察区南侧，最低点位于场地北侧，高程187.80m,相对最大高差达18.5m,区内主要坡顶、坡脚均存在居民建筑，地形坡角多为3〜25°,局部为陡坡、陡坎，覆盖层主要为素填土。2地质构造场地位于珍溪场向斜南翼翘起端东侧，无断层发育。据调查，岩层产状为335。N25。，层面结合极差，属软弱结构面。岩体中发育有两组裂隙：①210°Z68°,裂隙面较光滑，延伸较平直，长L2〜3.2m,局部呈张开状，裂隙宽0.1〜0.5cm,间距1.0〜3.5m,充填泥质；裂隙面结合差，属硬性结构面。②132°Z70°,裂隙面粗糙，弯曲延伸，长1.0〜2.3m,裂隙宽0.1〜0.5cm,间距1.0〜3.0m,泥质半充填，裂隙面结合差，属硬性结构面。3地层岩性据调查和钻探揭示场地覆盖层为第四系全新统人工填土层（QT）,基岩为侏罗系中统沙溪庙组泥岩（Ls）。各类岩土层特征如下：1、第四系全新统人工填土层（QL）：素填土：杂色，稍湿，由泥岩、砂岩碎、块石土等组成，中间粉质粘土充填，结构松散〜稍密，局部架空，由人工堆填而成，堆填时间约8年；粒径大小一般3X25cm,局部可达45cm以上，硬质含量约占30-42%,土层最大厚度约6.9m（ZK6）,分布于大部分场地。2、侏罗系中统沙溪庙组（，s）：泥岩：紫红色，泥质结构，中厚层状构造，易风化崩解，以粘土矿物为主，局部含砂质较重；强风化岩芯呈碎块及散粒状，质软，锤击生哑，风化裂隙发育；中等风化岩芯较完整呈柱状，节长6〜36cm,强度较高，节理裂隙不发育，为场地的主要岩性。3.4水文地质条件1、勘察场地内地层主要为第四系全新统人工填土层及侏罗系中统沙溪庙组地层，地下水主要为松散介质孔隙水及基岩裂隙水，由于区内地形坡角较陡，地表水径流条件较好，但区内土层结构较散，部分地表水也会下渗至岩土体中。勘察区在钻孔揭露深度范围内地下水贫乏。2、钻孔施工结束后，提干孔内施工残余水，第二日进行水位观测，观测发现该场地内所有钻孔内均未见恢复水位，故场地第四系孔隙水和基岩裂隙水贫乏。据调查拟建场区无污染源及污染物，土属未污染土，按《岩土工程勘察规范》GB50021-2001（2009年版）附录G判定该场地环境类型为H类；按《岩土工程勘察规范》GB50021-2001（2009年版）第12.1条和经验判定，地下水和土对混凝土结构具微腐蚀性，对钢筋混凝土中钢筋具微腐蚀性，土对钢结构具微腐蚀性。3.5不良地质现象及地质灾害经工程地质调查和钻探揭露，勘察场地及影响范围内除存在滑坡外，未见危岩崩塌、泥石流、溶洞等不良地质现象。滑坡的规模、特征和稳定性详见本报告第5章。4、岩土设计参数取值1、滑体素填土：天然重度2O.OKN/m3,饱和重度21.0KN/m3。2、滑面滑带土层：饱和抗剪强度c=5Kpa,中=21.5°。3、滑床：（1）中风化泥岩：天然重度25.5KN/m3,饱和重度25.7KN/m3；天然抗压强度标准值5.39Mpa,饱和抗压强度标准值3.51Mpa；岩体抗剪强度标准值：c=2OOKPa（经验值）；①=26°（经验值）；泊松比030（经验值）；岩体水平抗力系数取65MN/m3；岩石与锚固体极限粘结强度标准值380kpa；挡墙基底摩擦系数强风化泥岩取0.30,挡墙基底摩擦系数中风化泥岩取0.45。(2)岩质地基承载力特征值计算：根据《建筑地基基础规范》(DBJ50-047-2016)4.2.3条地基承载力特征值应根据地基极限承载力标准值乘以地基极限承载力分项系数确定，岩石地基极限承载力分项系数取0.33；据《工程地质勘察规范》(DBJ50-043-2016)9.3.2条中等风化基岩地基极限承载力标准值由岩石天然抗压强度标准值乘以地基条件系数确定，地基条件系数取1.1(中等风化岩体为较完整)，即中等风化泥岩的承载力特征值为1851Kpa。5、设计原则(1)边坡安全等级：一级(2)边坡防护工程设计安全系数：1.35(3)边坡重要性系数：1.1(4)结构设计安全使用年限及设计基准期：50年(5)抗震设防烈度：6度(0.05g)(6)设计荷载：边坡地面人群及绿化使用荷载lOKPa6、计算遵循的主要规范(1)《建筑边坡工程技术规范》(GB50330-2013)(2)《建筑基坑支护技术规范》(JGJ120-2012)；(3)《建筑地基基础设计规范》(GB50007-2010)(4)《混凝土结构设计规范》(GB50010-2010)(2015年版)(5)《建筑结构荷载规范》(GB-50009-2012)7、边坡计算7.1、抗滑桩综合分析(2-2剖面)桩、板计算条件1.总控制信息
