The paper carries out mechanical analysis of the weight distributing of goods in loading container based on analysis of packing and tansporting environment, and draws the formula of the ratio of the weight of loading goods and the maximum loading weight W/W0, and the length distributing ratio of loading goods α=l/L under the condition that the bending quadrature produced by part load is within the range of the maximum bending quadrature. It also gives the graph that the sum deflection of mudsill and underside girder can reach high-point value with the length of bottom distributing varying, when the loading amounts of container of 20ft and 40ft are given. Furthermore, it provides the relation graph of an eccentric rate of loading goods and the allowed loading amount. For on-site safety loading work, it has certain guidance and reference value.
