One is to utilize ships and special meshwork to draw or push away the sea-ice on the sea, and the other is to set up some barriers made up of several pillars at coast, which is vertical to the main direction of sea-ice movements, and to centralize the moving sea-ice along the bar according to the characteristic that sea-ice moves with wind and sea-flow, which is easy to carry and debark the ice.

一是利用船舶和特殊网具在海上拉冰；二是在海岸边建一个与海冰主运动方向相垂直的由若干个柱子组成栅栏，利用海冰沿按风和流的运动方向而移动的特点，将运动的海冰集聚在栅栏前，便于把冰搬运上岸。

The first one is to build a slope of certain gradient and length according to the main direction of sea-ice movements at coast, to make the sea-ice assembling under the slope climb along the slope by virtue of environmental driving force of wind and flow, and then to take out sea-ice cubes to desalinize after sea-ice falling into the ice-storing section when it reaches the top of the slope.

一是在岸边按海冰运动的主方向修建有一定坡度和长度的斜坡，利用环境驱动力的作用，使聚集在斜坡下的海冰沿着斜坡向上爬升，上升到坡顶后跌入贮冰区内，再从贮冰区中取出海冰块进行淡化。

Therefore, the following works was conducted: 1 Setting up different types combination failure model of ice sheet interaction with semi-breakwater, and considering different actual conditions of crushing, bending and bucking failure in the process of ice pileup when ice sheet acts on the semi-breakwater; 2 Applying analysis of non-continuous transmutation for the numerical simulation. This method is a new numerical analysis method of simulating mechanics response of dispersoid, it has a broad application prospect for the simulative questions of ice sheet moving, deforming, breaking and circumvolving after ice sheet occur pileup.

为此，具体进行： 1 建立冰排作用于半圆堤时的不同破坏类型的组合破坏模式，能够考虑到半圆型防波堤前海冰堆积过程中，由于水位的变化和堤前冰块堆积到一定程度在低水位时触底，冰排作用于半圆堤时可能会发生弯曲、挤压、压曲等不同类型的破坏的实际情形。

A synthetic method to recognizing ice situation combining Froude,density of drift ice and accumulated negative temperature is produced,the ice process and schedule along the route is predicted and the characteristics and influencing factors of conveying in ice period is analyzed,and the ice danger prevention measures are also advised.

提出了采用Fr数、流冰密度、负积温综合判别不同冰情的方法，预测了南水北调中线工程冬季输水不同冰情的时空分布特征，并初步分析了冰期输水的特性及影响因素，提出了冰期输水冰情防治和预防措施等方面的建议。
