铺缆船用电缆埋设犁土壤挖掘阻力计算

传统的计算埋设犁土壤挖掘阻力的方法一般采用经验公式计算。经验公式依赖丰富的试验数据，且只能适应特定形状和尺寸的埋设犁。由于埋设犁的形状和尺寸各不相同，基于经验公式计算土壤挖掘阻力的方法准确性不高。根据土力学基本原理，在力学分析的基础上，运用数学方法进行公式推导，得到用于计算不同形状尺寸埋设犁挖掘阻力的理论方法，解决依赖经验公式计算土壤挖掘阻力的局限性。

Soil Excavation Resistance Calculation of Cable Burying Machine for Cable Layer

The traditional soil excavation resistance calculation method of burying machine is generally to use the empirical formulas. The empirical formulas rely on the abundant test data and can only be adapted to the burying machines with specific shapes and sizes. Due to the different shapes and sizes of burying machines, the soil excavation resistance calculation method based on the empirical formulas is not very accurate. According to the basic principle of soil mechanics, on the basis of mechanical analysis, the mathematical method is used for the formula derivation, and the theoretical method for calculating the excavation resistance of burying machines with different shapes and sizes is obtained, which solves the limitation of relying on the empirical formulas to calculate the soil excavation resistance.
