    傳統上擋土墻穩定性分析常采用以安全系數為度量指標的定值法

    設計擋土墻時,一般先根據擋土墻所處的條件(工程地質、填土性質、荷載情況以及建筑材料和施工條件等)憑經驗初步擬定截面尺寸,然后進行擋土墻驗算。若不滿足要求,則應改變截面尺寸或采用其他措施。
    In the design of retaining wall, the cross-section size is initially drawn up based on experience according to the conditions (engineering geology, filling properties, load conditions, building materials and construction conditions) of the retaining wall, and then checking calculation of the retaining wall is carried out. If the requirement is not met, the section size should be changed or other measures should be adopted.
    擋土墻的穩定性驗算通常包括抗傾覆穩定性和抗滑移穩定性驗算,當地基軟弱時還要進行地基深層穩定驗算。
    The stability checking calculation of retaining wall usually includes the checking calculation of anti-overturning stability and anti-sliding stability. When the foundation is weak, the checking calculation of deep stability of foundation should be carried out.
    傳統上擋土墻穩定性分析常采用以安全系數為度量指標的定值法,但定值設計法無法考慮土的各項物理力學指標的隨機性,導致在工程中假山制作 不銹鋼鑄件 鋁箔真空袋 七孔梅花管 hdpe硅芯管 液壓鋼壩 PVC軟管 飛行激光打標機 瀝青保溫泵某些擋土墻按定值法估計的安全系數是足夠的,而投入使用后卻很快發生了破壞。對于將可靠度方法引入擋土墻的設計計算中,部分學者已經做了一些工作。
    Traditionally, the fixed value method is often used to analyze the stability of retaining walls, but the fixed value design method can not consider the randomness of various physical and mechanical indexes of soil, which results in that the safety factors estimated by the fixed value method are sufficient for some retaining walls in engineering, but they are destroyed very quickly after being put into use. Some scholars have done some work on introducing reliability method into the design and calculation of retaining wall
