Core-wall earth and rockfill dam crest settlement reservation calculation method
The invention discloses a core-wall earth and rockfill dam crest settlement reservation calculation method. A core-wall earth and rockfill dam crest settlement reservation structure comprises an upstream gradient changing line, a downstream gradient changing line and a top gradient changing line, the method mainly comprises the steps of establishing a three-dimensional coordinate system, calculating vertex coordinates of the upstream gradient changing line and the downstream gradient changing line, calculating locus equations of the upstream gradient changing line and the downstream gradient changing line, and calculating a locus equation of the top gradient changing line, the locus equations of the upstream gradient changing line and the downstream gradient changing line are obtained by taking two jetty heads and an upstream gradient changing line vertex or a downstream gradient changing line vertex as three coordinate points, and the top gradient changing line locus equation is obtained by taking the two jetty heads and a top gradient changing line vertex as three coordinate points. The method has the advantages that the calculation is simple, complex finite element calculation does not need to be carried out, the reliability is high, the settlement position of each part of a dam body is calculated according to the characteristics of dam body settlement, construction and positioning are convenient, the positions (coordinates) of all contour points of any section can be determined according to the parabolic locus equation, and construction is convenient.
本发明公开了一种心墙土石坝坝顶超高计算方法，心墙土石坝坝顶超高结构包括上游变坡线、下游变坡线及顶部变坡线；主要包括建立三维坐标系步骤，计算上游变坡线、下游变坡线顶点的坐标步骤、计算上游变坡线、下游变坡线的轨迹方程步骤和计算顶部变坡线的轨迹方程步骤，通过两坝头和上游变坡线顶点或者上游变坡线顶点三个坐标点，得到上游变坡线、下游变坡线的轨迹方程，通过两坝头和顶部变坡线顶点三个坐标点，得到顶部变坡线轨迹方程。本发明计算简单，不必进行复杂的有限元计算；可靠性高，根据坝体沉降的特点计算每部分的沉降位置；方便施工定位，可以根据抛物线轨迹方程，定出任意剖面各轮廓点的位置（坐标），便于施工。
