首先以一種簡單實用的輪齒邊緣切矢量的數學表示方法取代了經典的微分表達式，大大簡化了幾何邊緣接觸的求解，使復雜曲面的幾何邊緣接觸分析得以實現；其次又採用數值搜索與數學規劃法求解了邊緣接觸的主方向和承載接觸問題，為高重合度弧齒錐齒輪承載嚙合全過程的數值模擬提供了完整的方法。 -
The spiral sheet metal carry the lotus test to be apply in the bearing power test of the deep foundation soil and water table following foundation soil extensively because the ability goes into the surface of earth is following the certain depth area curve carry on test, according to the element that the spiral sheet metal carries the lotus test, through contrast with plate load test, the spiral sheet metal carries the lotus test to be applicable to the shallow storey foundation soil equally, the size of the spiral sheet metal time area concentration diagram is not big to the test result influence, the spiral sheet metal carries the bearing power of the lotus test assurance to no longer carry on the depth area curve redress
摘要螺旋板載荷試驗因能旋入地面以下一定深度進行試驗而廣泛應用於深層地基土及地下水位以下地基土的承載力測試，根據螺旋板載荷試驗的原理，經與平板載荷試驗對比，螺旋板載荷試驗同樣適用於淺層地基土，螺旋板面積的大小對試驗成果影響不大，螺旋板載荷試驗確定的承載力不再進行深度修正。 -
