摘要： A foundation for a retaining wall-type of structure acted upon by a principal force tending to slide same in a predetermined direction is anchored by a plurality of slide resisting walls. The slide resisting walls extend parallel to the predetermined direction in which the foundation tends to slide. The upper portions of the slide resisting walls are embedded in a concrete mass. The lower portions of the slide resisting walls project downwardly from the concrete mass into the earth, and are solely in engagement with the earth and not with concrete.

摘要： A method for preventing or greatly reducing damage to building foundations resulting from the swelling of moisture-expansive clay beneath and about such foundations. The method includes the steps of first forming a trench about the foundation, the trench extending well below the basement or on-grade floor slab of that foundation, and then substantially filling the trench with an extrudable plastic mass of hydrated lime and water to help stabilize the moisture-expansive clay and to provide a yieldable buffer capable of being displaced upwardly to accommodate horizontal expansion of the clay beneath and about the foundation, thereby relieving lateral stresses and reducing upward forces against the floor slab.
摘要翻译：一种用于防止或大大减少由于在这种基础之下和周围的膨胀土而膨胀的建筑物基础造成的损害的方法。该方法包括以下步骤：首先在基础上形成沟槽，沟槽远远延伸在该基础的基底或一级楼板之下，然后用可挤出的熟石灰和水的塑料块基本上填充沟槽以帮助稳定水分膨胀粘土，并提供能够向上移位的可屈服缓冲剂，以适应地基下方和周围的粘土的水平膨胀，从而减轻横向应力并减小对地板的向上力。
