地基承载力地基承载力foundation bearing capacitydili ehengzaili地基承载力(允undatio。bearing。apaeity)地基土体单位面积上承受荷载的能力。用以衡量地区土体通行能力和军事工程建筑场区的地质条件。一般分为极限承载力和允许承载力。前者是使地基土体达到完全剪切破坏时的最小荷载;后者是在满足地基强度和军事建筑物、构筑物容许沉降量时，地基土体所能承受的最大荷载。确定容许承载力的方法有规范查表、理论计算、原位测试和经验类比等。规范查表法是根据土的类别和物理力学性质指标，查阅有关规范中相应的表格而求得相应的数据。理论计算法是根据土的物理力学性质指标、基础的宽度和埋深，按下式计算:凡=N。下B十ND了尸D+NcC式中凡为地基土的承载力(吨/米2);N。、N。、N。为承载力系数，均按地基土的内摩擦角沪值查表;v为基础底面以下土的天然容重(ll屯/米3，地下水位以下取浮容重);了。为基础底面以上土的加权平均容重(吨/米3，地下水位以下取浮容重);B为基础底面宽度(米);D为基础埋置深度(米);C为地基土的内聚力(吨/米2)。原位侧试法包括动力触探、静力触探、荷载试验和旁压试验等方法。动力触探法是根据落锤将探头击人土中到规定深度时的锤击次数，再查表确定容许承载力。静力触探是以静力将探头压人土中，利用探头内的阻力传感器，测定比贯人阻力或锥头阻力和侧壁摩擦力来确定容许承载力。荷载试验是于现场安装试验设备，分级加荷载，每级荷载施加后，按规定的时间测读沉降量至稳定时，再施加下一级荷载，直至按规定的标准确认地基土已达破坏状态即停止加载，然后作出荷载一沉降关系曲线护一S曲线)来确定容许承载力。旁压试验是通过旁压仪在钻孔内对孔壁施加横向压力，使土体产生变形，测出压力和相应变形量，绘制出实际作用于土体的压力和变形关系曲线来确定容许承载力。此外，用工兵圆锥仪可快速测定军用道路的路基极限承载力;还可用空投圆锥仪测定勘察人员不易到达的地区的地基承载力，它是按其落地后的闪光信号来判断可通行性。经验类比法是根据对地区地层的分布和性质所积累的经验或调查研究的成果来确定容许承载力。影响地基承载力的因素有土体的形成年代、成因类型、物理力学性质、地下水作用和军事设施的性质、结构类型、基础尺寸及埋深等。当承载力不能满足军事设施要求时，要对土体进行加固，以提高其承载力。加固方法有:碾压夯击、换土垫层、振动挤密、排水固结、植桩和化学加固等。对于淤泥、沼泽、滩涂、泛滥区等难以通行的地段，可采用“集料一土工布一土基”系统(AFS系统)等措施予以克服。(傅加豪)
