贝壳砂是港口工程和海洋工程陆域形成的一种新的回填料,贝壳砂的贝壳含量是影响贝壳砂工程特性的主要因素,在控制回填的贝壳砂质量时,需检测回填贝壳砂的贝壳含量、贝壳比重等指标。结合LNG接收站工程实践,笔者研究了贝壳砂质量检测的方法,并将其应用于工程实践,取得了较好的效果。

Shelly sand is a new backfill for land reclamation for port and oceanic engineering.The content of shells in the shelly sand is the main factor affecting the engineering characteristics of the shelly sand.In order to control the quality of the shelly sand as a backfill,it is necessary to examine the content and the specific weight of the shelly sand.The authors studied a method for checking the quality of shelly sand in the light of a terminal project and used it on the engineering practice with satisfactory results.
