公路渡船的设计,主要包括渡船的稳定性验算和渡船的结构强度验算两个方面。前者计算之目的,在于了解渡船在空载和满载时之排水量、吃水深以及渡船作小角度侧倾时之纵横倾度和载重汽车由码头引道驶入渡船时与渡船满载在河中行驶时之稳定性;后者计算之目的,在于求算渡船各部材所受内力大小,以便得出经济安全而又适用的结构设计断面。茲结合湖南省交通厅24公吨渡船标准设计作为实例,将渡船的设计方法概略介绍于下,尚望大家研究指正。
The design of highway ferry mainly includes the checking of the stability of the ferry and checking the structural strength of the ferry. The purpose of the former calculation is to understand the displacement of the ferryboat at no-load and full-load conditions, the draft and the longitudinal and transverse inclinations of the ferry when it is slightly angled and the time when the truck enters the ferry along the quay and when the ferry is fully loaded with the river Stability; the latter purpose of the calculation is to calculate the size of internal forces suffered by the ferry parts in order to arrive at economic and structural and structural safety section applicable. Combined with the standard design of the 24 mt ferry in Hunan Communications Department as an example, the design method of the ferry boat is briefly introduced below, and it is hoped that everyone will study and correct it.
