In highway construction, various foundations may be encountered. For soft soil foundation, certain measures should be taken, or there will be potential risk in the service of the highway, and even causing serious accident. The application of high-pressure gunite technique in highway foundation construction can improve its carrying capacity and reduce land subsidence. It is also applicable in artificial filled soil, sand, clay and silt clay foundation, so high-pressure gunite technique has very broad application prospect in highway foundation construction. Taking a highway project for example, this article explores the application of high-pressure gunite technique in highway foundation construction, which is of certain referential significance.%公路工程在施工的过程中，会遇到各种各样的地基，当公路工程遇到软土地基时，如果不采取一定的措施进行处理，将会给公路工程的安全适用埋下安全隐患，甚至会造成严重的安全事故。高喷灌浆技术在公路地基施工中的应用，能够提高公路地基的承载能力、降低土地沉降量，并且适用于人工填土、砂土、粘性土、淤泥质粘土等地基中，因此高喷灌浆技术在公路地基施工中具有非常广泛的应用前景。文章以某公路工程为例，探析了高喷灌浆技术在公路地基施工中的应用，以供参考。
