در این مقاله به منظور بررسی اندرکنش ماسه کربناته و شمع، مجموعه­ای از آزمایش­های برش مستقیم انجام شده است. برای رسیدن به این هدف، شمع­ها نیز به دوصورت فلزی و بتنی در نظر گرفته شده است. مصالح نماینده شمع در جعبه برش پایین و مصالح خاکی در جعبه برش بالا قرار گرفته است. متغیرهای اصلی این پژوهش عبارت است از مصالح شمع (فولادی و بتنی)، سطح تنش نرمال، دانسیته نسبی خاک، زبری سطح شمع و زاویه سطح برش نسبت به شیارهای ایجاد شده بر روی مصالح شمع. نتایج بدست آمده نشان می­دهد که پارامترهای مقاومت برشی بدست آمده در مرز بین شمع و خاک تابعی از عوامل مختلف همچون خصوصیات ژئوتکنیکی خاک و زبری سطح شمع است. به طوریکه با افزایش دانسیته نسبی خاک و افزایش زبری سطح شمع، مقدار زاویه اصطکاک بسیج شده در سطح بین شمع و خاک افزایش می­یابد. با یک سطح زبری یکسان، مقدار زاویه اصطکاک بین شمع و خاک در نمونه­های فولادی بیشتر از نمونه­های بتنی است. نتایج آزمایش­ها نشان می­دهد مقاومت برشی بین صفحات و ماسه در حالت جهت برش عمود بر جهت شیارهای صفحات بیشتر است. خردشدگی در ماسه کربناته بعد از اعمال تنش برشی در انتهای آزمایش در صفحات فولادی بیشتر از صفحات بتنی است.
