The object of this proposal is to investigate the effect of gravel-sized particles on the liquefaction resistance of gravelly-sand specimens. The goal is to show quantitatively how the liquefaction potential of sand is effected by inclusion of gravel particles. Since sand is readily accepted as liquefiable bu most engineers, the liquefaction potential of several gravelly soils will be compared to that of sand. Case histories and dynamic laboratory testing will be used to show that gravelly soil is liquefiable.

这项建议的目的是调查 砾石大小的颗粒对抗液化性能的影响 砾石砂标本。目标是证明 定量地说明砂土的液化潜力 受砾石颗粒的影响。因为沙子是 被大多数工程师认为是可以接受的， 几种砾石土的液化潜力将是 与沙子相比。案例历史和动态 实验室测试将用于显示砾石土， 是可以接受的
