【摘要】：斜坡式防波堤是常用的防波堤結(jié)構(gòu)型式,對(duì)于有抗震設(shè)防要求的斜坡式防波堤,斜坡式防波堤穩(wěn)定性計(jì)算還有一系列問題值得探討。本文作者基于Ashdod港口主防波堤延長(zhǎng)段工程項(xiàng)目對(duì)對(duì)斜坡式防波堤穩(wěn)定性展開了一系列研究。利用有限元軟件PLAXIS和常規(guī)軟件Geo-slope進(jìn)行對(duì)比計(jì)算,探究PLAXIS在工程應(yīng)用中的優(yōu)劣,此外從工程實(shí)踐角度,研究探討常用幾種地基處理方式對(duì)斜坡式防波堤設(shè)計(jì)的影響,并對(duì)斜坡式防波堤進(jìn)行了動(dòng)力模塊分析,更對(duì)斜坡式防波堤的穩(wěn)定性影響因素進(jìn)行了深度研究。本文對(duì)國(guó)內(nèi)外邊坡抗震研究的相關(guān)資料進(jìn)行了較為系統(tǒng)的整理,將邊坡穩(wěn)定性研究方法做了檢索和闡述。針對(duì)斜坡式防波堤穩(wěn)定性計(jì)算中的突出問題進(jìn)行了研究。通過數(shù)值模擬得出,斜坡式防波堤一般是堤頭貫通失穩(wěn),整體滑移,導(dǎo)致堤角處隆起從而破壞;本文得出土體強(qiáng)度,防波堤的尺度以及自然條件等對(duì)斜坡式防波堤的穩(wěn)定性有著重大的影響,而高震區(qū)的防波堤設(shè)計(jì)需重視不同地基處理所帶來的效果。通過本文的研究,為今后斜坡式防波堤的工程計(jì)算和設(shè)計(jì)提供了參考和依據(jù)。
[Abstract]:Slope breakwater is a common structural type of breakwater. There are still a series of problems to be discussed in the stability calculation of sloping breakwater. Based on the Ashdod port main breakwater extension project, the author has carried out a series of research on the stability of the slope breakwater. The finite element software is used to study the stability of the slope breakwater. The PLAXIS is compared with the conventional software Geo-slope. This paper probes into the merits and demerits of PLAXIS in engineering application. In addition, from the point of view of engineering practice, the influence of several kinds of foundation treatment methods on the design of slope breakwater is studied, and the power module analysis of slope breakwater is carried out. Furthermore, the factors affecting the stability of slope breakwater are studied in depth. In this paper, the relative data of slope seismic research at home and abroad are systematically sorted out. The research method of slope stability is searched and expounded. The prominent problems in the stability calculation of slope breakwater are studied. This paper concludes that the strength of soil, the scale of breakwater and the natural conditions have great influence on the stability of slope breakwater. The design of breakwater in high seismic area should pay attention to the effect of different foundation treatment. Through the research of this paper, it provides a reference and basis for the engineering calculation and design of slope breakwater in the future.
