【摘要】 “禹衡”岩土软件包括三部分内容：深基坑支护功能块(YHZJK)，边坡平面稳定分析功能块(YHBP2)和边坡楔形块体稳定分析功能块(YHWED3)。 深基坑支护功能块(YHZJK)是“禹衡”岩土软件开发的重点。这部分功能块编制的理论依据主要有：《建筑基坑支护技术规程》(JGJ 120-99)，等值梁法，逐层开挖支撑力不变法。深基坑支扩功能块(YHZJK)能处理多种土层，多种支护类型的深基坑支护情况。在荷载方面可考虑满布附加荷载，条形附加荷载，以及水的作用。对悬臂式支撑和单层支点支撑，可按规范方法或等值梁法进行设计计算。对多层支撑，可选用逐层开挖支撑力不变法进行设计计算。深基坑支护功能块(YHZJK)的主要功能有：对支护结构进行嵌固深度的设计；计算整个桩身的剪力和弯矩；对任意深度的剪力和弯矩进行查询；在截面承载力计算方面，能进行圆形截面均匀或局部均匀配筋的设计和复核；在结果显示方面，除了生成数据结果文件以外，还能在菜单中直接控制AutoCAD的使用，可直接生成土压力图，剪力图，弯矩图以及配筋图。 “禹衡”边坡平面稳定分析功能块(YHBP2)能确定有软弱面土坡的安全系数。静力或动力安全系数均可计算，同时，还可考虑渗流的情况。 “禹衡”边坡楔形块体稳定分析功能块(YHWED3)能分析静力和动力情况下楔形块体的安全系数。可考虑张裂缝以及水的作用。通过输入地震力系数或地震加速度波实现对地震作用的模拟。同时，可考虑水平和竖向荷载的作用。 本文的创新点在于：(1)利用了AutoCAD的ActiveX自动化服务功能(ActiveX Automation Server Capabilities)，实现了Visual Basic和AutoCAD的无缝连接；(2)实现了圆形截面的均匀和非均匀配筋设计；(3)推导了楔形块体在三个方向地震波作用下的动力稳定安全系数计算公式，并研究了由于相位差而导致的楔体不同部位地震系数的差异。更多还原

【Abstract】 YuHeng" geotechnical software includes three parts: deep foundation pit supporting function block(YHZJK), slope analysis function block (YHBP2) and wedge stability analysis function block (YHWED3) .Deep foundation pit supporting function block is the most important part of "YuHeng" geotechnical software. The theory of this block is based upon the following specifications or methods: <<Technical Specification for Retaining and Protection of Building Foundation Excavations>> (JGJ 120-99), equivalent beam method and the step excavations with fixed retaining force method. The YHZJK function block can deal with the deep foundation pit support design in case of different soils and support types. Besides, the YHZJK function block can take into account the uniformly distributed additional load, the strip additional load and water action. The specification method and the equivalent beam method are used to design the cantilever retaining structure and single support retaining structure. And the step excavations with fixed retaining force method is used for multi-support retaining structure. The functions of the YHZJK are as following: designing of the embeding depth of the retaining structure; calculating of the shearing force and moment of stake; querying of the shear force and moment of random depth. For section carrying capacity, it can design and check the round section equally or unequally reinforced. On the side of output, besides the data result file, it can also plot the soil pressure force drawing, the shear force drawing, the moment force drawing and reinforced steel drawing with the menu control of Autocad."YuHeng" slope stability analysis function block can get the safety factor of the soil slope with weak faces. The static and dynamic safety factor can be calculated. At the same time, the seepage effect can be considered."YuHeng" wedge stability analysis function block can analyze the static and dynamic wedge safety factor on the action of tension fissure and water. Simulate the earthquake action by input the earthquake force coefficient or the earthquake acceleration wave. At the same time, the horizontal and vertical load can be considered.The new ideas of this paper are as following: (1) using of AutoCAD ActiveX Automation Server Capabilities to realize the seamless joint of AutoCAD with Visual Basic. (2) Designing of the round section equally or unequally reinforced. (3) Studying of the wedge dynamic stability under earthquake acceleration waves from three directions, and giving out the results that earthquake coefficient varies with different part of wedge because of phase shift.更多还原
