    <h3 class="section-title">一、场景核心关键要素识别</h3>

    <div class="sub-section-title">（一）构筑物要素</div>
    <div class="element-item">
      <strong>多层高墩高架桥梁：</strong>大截面钢筋混凝土方形高墩，多层桥梁梁板架空跨越山谷，桥梁基础、桥台埋置于山体填土内，属于山区高墩桥，桥梁基础抗冲刷、抗滑坡要求极高。
    </div>
    <div class="element-item">
      <strong>大口径圆管排水涵洞：</strong>钢筋混凝土波纹管涵，横穿路基土体，上游汇水通过管道直排天然溪沟，承担山体雨水、地下水导排功能，为桥梁配套防洪排水构筑物。
    </div>
    <div class="element-item">
      <strong>边坡支护设施：</strong>左侧山体边坡铺设绿色防尘密目安全网，仅简易覆盖，无锚杆、喷砼等永久边坡防护结构。
    </div>

    <div class="sub-section-title">（二）场地地貌要素</div>
    <div class="element-item">
      <strong>开挖回填土体：</strong>大面积裸露松散黄褐色回填土方，土体无压实硬化、无护坡衬砌，坡面陡峭，混杂碎石、大块孤石。
    </div>
    <div class="element-item">
      <strong>天然山涧溪流：</strong>涵洞出水形成湍急河道，河床乱石堆积，水流持续冲刷涵洞出口及下方土体。
    </div>
    <div class="element-item">
      <strong>施工辅助材料：</strong>边坡防尘绿网、碎石垫层、开挖弃土堆、原生野生灌木植被。
    </div>

    <div class="sub-section-title">（三）环境区位要素</div>
    <div class="element-item">
      深山峡谷区域，山体植被茂密，降雨汇流量大；属于在建山区高速配套排水工程，土方回填阶段，未完成场地永久防护、硬化施工。
    </div>

    <h3 class="section-title">二、现场潜在安全隐患分类梳理</h3>

    <div class="hazard-category">
      <div class="hazard-category-title">
        <span class="hazard-icon">⛰️</span>
        <span>（一）边坡坍塌、滑坡类隐患</span>
      </div>
      <div class="hazard-sub-item">
        <h5>回填土体松散失稳</h5>
        <p>涵洞两侧大面积堆填素土，未分层碾压密实，坡面无浆砌/喷锚永久护坡，仅靠简易绿网覆盖，遇降雨后土体饱和，极易发生浅层溜塌、大规模滑坡，直接冲击桥梁桥墩、掩埋涵洞。</p>
      </div>
      <div class="hazard-sub-item">
        <h5>山体原生边坡防护不足</h5>
        <p>左侧山体岩壁仅铺设防尘网，无主动防护网、截排水沟，暴雨时山体碎石、浮土滑落，砸损桥墩及施工区域。</p>
      </div>
      <div class="hazard-sub-item">
        <h5>孤石滚落风险</h5>
        <p>边坡及沟谷散落大量裸露大块孤石，土体冲刷掏空后孤石失稳滚落，威胁桥梁结构与现场作业人员。</p>
      </div>
    </div>

    <div class="hazard-category">
      <div class="hazard-category-title">
        <span class="hazard-icon">🌊</span>
        <span>（二）水流冲刷、水毁结构类隐患</span>
      </div>
      <div class="hazard-sub-item">
        <h5>涵洞出口淘空风险</h5>
        <p>管道出水直排土体坡面，湍急水流持续冲刷涵洞出口基底，长期冲刷会掏空管道基础，造成涵管沉降、断裂、渗漏，丧失排水功能。</p>
      </div>
      <div class="hazard-sub-item">
        <h5>桥梁基础水蚀破坏</h5>
        <p>溪沟流水紧邻桥台、桥墩下方，边坡土体被流水持续侵蚀，逐步掏空桥梁承台、桩基覆土，降低桥梁整体抗倾覆、抗滑移能力，诱发桥墩倾斜。</p>
      </div>
      <div class="hazard-sub-item">
        <h5>山洪漫溢风险</h5>
        <p>山区暴雨易形成山洪，若涵洞排水能力不足，积水漫过回填土路基，会大面积软化土体，加剧滑坡灾害，甚至倒灌侵蚀桥梁下部结构。</p>
      </div>
    </div>

        <span>（三）施工作业人身安全隐患</span>
      </div>
      <div class="hazard-sub-item">
        <h5>临边无防护设施</h5>
        <p>陡峭土坡、沟坎边缘未设置防护栏杆、警示围挡，人员巡查、作业时易失足坠落沟谷。</p>
      </div>
      <div class="hazard-sub-item">
        <h5>场地通行条件恶劣</h5>
        <p>地面为松散泥土、碎石，雨天泥泞湿滑，无硬化施工便道，车辆、人员通行易打滑侧翻、摔倒。</p>
      </div>
      <div class="hazard-sub-item">
        <h5>无安全警示标识</h5>
        <p>现场未设置滑坡、山洪、陡坡危险警示牌，外来人员、施工人员无法提前预判风险。</p>
      </div>
    </div>

    <div class="hazard-category">
      <div class="hazard-category-title">
        <span class="hazard-icon">🌿</span>
        <span>（四）环保及次生灾害隐患</span>
      </div>
      <div class="hazard-sub-item">
        <h5>水土流失污染河道</h5>
        <p>裸露土体无完整护坡，雨水冲刷泥土汇入溪流，造成水体泥沙超标，破坏山区河道生态。</p>
      </div>
      <div class="hazard-sub-item">
        <h5>防尘网失效引发扬尘</h5>
        <p>绿网仅简易铺设，未压实固定，大风、降雨后破损脱落，土方裸露产生扬尘，同时破损网体易堵塞涵洞进水口，造成排水堵塞积水。</p>
      </div>
    </div>

      <div class="hazard-category-title">
        <span class="hazard-icon">🏗️</span>
        <span>（五）构筑物长期运行隐患</span>
      </div>
      <div class="hazard-sub-item">
        <h5>涵管回填不均匀沉降</h5>
        <p>涵管上方回填土未规范分层压实，后期易出现不均匀沉降，导致波纹管变形、接口开裂渗漏。</p>
      </div>
      <div class="hazard-sub-item">
        <h5>缺少山体截排水系统</h5>
        <p>边坡顶部未设置截水沟，山体地表水直接渗入回填土体，持续软化基底，加速滑坡、水毁病害发展。</p>
      </div>
    </div>
