工程中计算土坝坝体沉降一般沿用地基沉降计算的分层总和法,而坝体沉降变形的压缩应力是其自重应力,它沿高度是直线变化的,不象地基中那么复杂,因此,可以由积分法导出其计算公式。现将计算公式推导如下:在坝高为H的坝体中取一厚度为dh的土层,其沉降为: In engineering calculation, earth dam body settlement generally follows the method of stratified summation for calculation of settlement of foundations, and the compressive stress of settlement deformation of the dam is its own weight stress. It varies linearly along the height and is not as complex as the foundation. Therefore, it can be The calculation formula is derived from the integral method. The formula is deduced as follows: In a dam with a height of H, take a layer of soil with a thickness of dh. The settlement is:
