[摘要] 在公路、鐵路等工程中，對(duì)填土路基進(jìn)行適當(dāng)碾壓，是保證路基施工質(zhì)量的重要環(huán)節(jié)。碾壓次數(shù)不夠會(huì)影響路基質(zhì)量，同樣，次數(shù)過(guò)多不僅不經(jīng)濟(jì)，也有可能降低土體強(qiáng)度及剛性，帶來(lái)負(fù)面影響。介紹了新開發(fā)的一種落球式便攜剛性檢測(cè)儀，可以快速地測(cè)試碾壓后的土基壓縮彈性模量，進(jìn)而有效地對(duì)填土碾壓質(zhì)量進(jìn)行管理。

Abstracts: In engineering, it is an important key, though compressing the foundation of filling, to guarantee the construct's mass of road foundation. The times of compressing will of Fect the quality of compressing mass. Adopting the machine EH-FWD-B which was developed by Sichuart Central Inspection Co., Ltd, through testing the modulus of compression can manage the compressing mass of filling validly.
